Pokémon X/Y- Pokémon has high replay value, and with so many to catch, well it takes forever and a half to catch 'em all. Plus, with Internet connection, you can duke it out and trade with rival trainers around the world. It can keep you entertained for very long periods of time. Definitely one you could use time and time again.

Kongregate on my computer- Kongregate is a gaming website run by Gamestop and it has many free online games. So many to keep you busy for... A long time. So this website is going on the list, for sure!

Any good FPS with good Internet supported Multiplayer, for obvious reasons.

Wow, this is a hard one. I would take in NASCAR dirt to Daytona because there is so much to do, NASCAR chase for the cup because there is lot to do in there, and Mario kart wii WITH internet connection.

I would pick Pokémon X for 3DS, the Legend of Zelda Ocarina of time for the Nintendo 64 and titanfall on the Pc

Sonic 3 & Knuckles, Streets of Rage 3, and Grand Theft Auto: San Andreas. Grand Theft Auto: San Andreas and Sonic 3 & Knuckles for being lengthy, and Streets of Rage 3 because it's my favorite game. The other two games are my favorites in the series that each of those games comes from.

DDR Extreme (PS2)
DDR Extreme 2 (PS2)
and maybe Tera

Hopefully, the Internet access point has no security password. Even if it did, it'd still be fun playing with the CPUs.
I would have my Wii with SSBB, Mario Kart Wii, and Animal Crossing: City Folk.

Let me see:

Pokémon X/Y for my 3DS - A lot of replay value, and i'm just too much of a fan of the pokémon series. It would take me ages to get bored, and if i could use the internet, then bam. So definitely X/Y

Super Smash Bros 3DS - Okay, it's not out yet, but when it does, i'd definitely take it with me. Plus online = tons of fun

Legend of Zelda, OOT 3D - Another game that i could replay anyday. Legend of Zelda is awesome.

I picked all the games for the same console. Was i able to pick other consoles as well?
I doubt my list would change though ^^

New Super Mario 3D land for my Nintendo 2DS, Plants vs Zombies 2 for my mobile phone and Inazuma Eleven 3 Bomb Blast!
Since I have access to internet I can play all RGR games on Vizzed

Paper Mario: The Thousand Year door, Luigi's Mansion and Pokemon XD Gale of Darkness.

awesomeguy279 : For me, it would be Mario Kart DS, Mario Kart 7 and Mario Kart 8 even though I don't own this new game

You are making me pick a system too? Come on. Do not do this to me.

Well, I would say my PS3, but I do not think that the games would last me long enough, as I have already played through most of the games I have wanted to. So, I will be going with my PS Vita. I would probably have to go with Steins;Gate, Sakurasou no Pet na Kanojo, and eh, Soul Sacrifice, just so that I have a game that I can have some action on. The first two are fantastic visual novels that would last me a long time, but I would also like some sort of action in my games if I were to be stuck in a room.

PES 5. It is a sports game so it doesn't matter how many times I play it. I can play that games for days. It also has a great edit mode so I can make what ever team I want and change the players about. Sonic Mega Collection Plus as that has multiple games and I enjoy Sonic a lot.  Spider man 2. Its my favorite Spider man game and I can easily play that games multiple times.

I would want to have a Wii with Wii Sports, Mario Kart Wii, and Namco Museum Megamix because all 3 of those games have a lot to do and I really enjoy playing them.

Oh man. I hate you right now.

I would probably have to go with Pokemon Emerald. Might as well have a Pokemon game with a lot of replaying ability, and is somewhat fun. It's also that only one that I played for more than a few hours.
I guess I would take Skyrim too, just for the heck of it, since I just purchased the DLC packs.
And just because I need something from my childhood... I would also take Mario Kart 64 over Tetris Plus, just because it is my childhood favorite.

Smash Bros. Melee - Man, I love this game too much. I could play it forever... Just please bring me a friend to play it with. Even if I don't get someone to play it with, it'll still be endlessly fun. Until I get too good and teams of level 9 Foxes all against me are beaten 4 times in a row with zero-to-death combos... Yeah. After years of playing the game daily, nonstop practice, I'd probably get that good.

Super Mario World - Though it has little replayability after you get all 96 exits, it would still be fun. I could compete with myself for the fastest time, eventually breaking the world record (if I haven't broken it already... hehehe). There's also lots of glitches to experiment with.

Either Skyrim or Elder Scrolls Online - These games are huge. I need a huge game to keep me occupied. Open world games would be perfect for this kind of situation. Skyrim seems very fun, but I would probably rather play Elder Scrolls Online (online play is schweet in open world games).

Dragon Quest 4 for the Nintendo DS. I have replayed that game a bunch of times in different challenge modes, and I'm sure I could continuously play it forming different sorts of challenges to help me stay sane.

Animal Crossing: New Leaf for the 3DS. It's an open-ended game that never ends, has Internet connection so I can interact with people, and even have a bunch of artificial animals to chat with. Though, considering I have it on the 3DS brings up the question if I can use the other apps on the system, or if it only lets me use things pertaining to the game (friend codes, the online adapter thing, stuff like that).

My last game depends if I can have this: An "In The Groove" machine with the ability to upload new step files on it at any time I want (would require Internet access to sites). Would be great to keep self exercised and burn off some energy if I begin to rage at a game or something.

The ITG machine does seem to be asking a bit too much out of such a simple question though. So I'd probably go with whatever the latest Tetris is with online capabilities, since that game can go on forever and always poses a challenge.

Hmm..

This is an very hard choice to make, there is so many games I played. How to choose just 3 of them ?

Well, I would have to go with Tekken Tag Tournament 2. I just have to have an Tekken game.

pokemon x : ( I summoned you cause it fit perfectly, you don't have to post haha )I could do an endless amount of work in there such as breeding for perfect IV's

Last but not least Desgia 4 that game never ends really.. all Desgia games dont I just like 4 the most

Pokémon X or Y, Pokémon OR or AS, and the newest call of duty so I can play a bunch of social games to chill out with.

If I was trapped in a room with 3 video games I would choose NHL 14, Pokemon Ruby, and Super Smash Bros Melee. Assuming that I had the correct consoles to play all of these games, of course.
