I usually like to wait for a few people to give their opinions first so that when I submit mine, it blends with the croud. Otherwise if mine is the first, I'll be the main target for people to attack if they oppose my view point.

Here is my opinion:

I picked offline. Online is fun, but to addictive, to many annoying people online, and there's no story. Offline games are the greatest games out there, they are the ones that are legendary. With Offline, you can enjoy a rich and deep story line with characters - games like the Final Fantasy games, Shenmue, Pokemon, Mario series, Zelda series, etc.. are all games that are very fun whose entertainment cannot be replicated by playing them online.

Halo series, for instance, I'm sure there are many who will play the game's online mode to death but will never consider playing hte campaign. Though the campaign can be played online in Halo 3, it cannot in Halo 2, and in my opinion, that's the greatest part of the Halo games, the story, the music, the characters, etc.

I'm not saying Online is bad, I do plan to make Online multiplayer games for Vizzed someday. I just think offline is better because that's where the real adventure is. If it wasn't for offline gaming we wouldn't know the famous gaming icons such as Mario, Cloud Strife, Laura Croft, Link, Mega Man, RYO HAZUKI, etc. I like the fact that Online play can always be different depending on who your playing with or against, but still, I'd much rather play thru a game with my GF in co-op (story mode) such has Halo campaign, splinter cell games, star wars battlefront, super smash bros brawl, lego star wars, lord of the rings, etc. And of course I love the games that are only 1 player, just lately I've only been playing games when I'm with my GF.

I voted online.
The best games are ones that have both online and offline. I think anyone who has played halo online has played campaign, and most of them have finished it.
Theres only so many times you can play campaign untill you can beat it on legendary in your lunchbreak. That means you have to play online with real players.

The ultimate in video games are games where you can play online and offline to unlock stuff (battle field 2 is sorta like this), but then you can play online with your new unlocks.
Im not sure about halo3 armour, but armour is nothing special unless it gives you more health or something to change your characters stats.

Online is more sociable. People might think that some people hardly come out anymore when there playing WoW and stuff, but you think about it, they just have a new group of friends that all share a comen interest.

and NOW you understand how i played over 550 hours of WoW in 3 months!!!! I had great friends their.. sure they just wanted me for my awesome DPS but still!

Ok, here's a challenge for you 2 guys, name your top 3 favorite games of ALL TIME, be honest too

Warcraft III: The Frozen Throne
World of Warcraft
Halo 2

And none of them i enjoy playing single player as much as i do with other HUMAN players... (also WHY doesnt Halo 2 have a bot system and Halo 3 BETTER have it )
