Good point. Although in Bully,your character was considered so horrible that no other school would accept him. I think the closest it got to a sequel was the scholarship edition. Bully would be a great game to base a sequel on. But Rockstar is busy milking GTA 5 to death.

Games we need:
-Metroid 5
-Undertale 2
-Mega Man Battle Network 7/Star Force 4/New Mega Man RPG Series
-Manhunt 3
-Bully 2
-Deadly Premonition 2
-Conker's Bad Fur Day 2 (Conker's Badder Fur Day?)
I'm most likely forgetting some great games, but those are a few just off the top of my head.

taterii :

Metroid 5: As long as they keep it like the original,not the 3D bulls--t.

Undertale: I never played it.

Mega Man Legends 3,I would love it,just fix the terrible controls.

Manhunt 3:That would be awesome,but Rockstar is busy milking GTA to death.

Bully 2: I would love see that.

Deadly Premonition 2: I never played it.

Conker's Bad Fur Day 2: Never played it.

I would love to see a proper sequel to SaGa Frontier.

Good question. I never really thought of it before now that you mention it... Well personally I would love to see a Super Mario Galaxy 3 title (I heard they're working on it for the Nintendo Switch, and not sure if it is the incoming Super Mario Odessy one (not sure if that's how you spell it) ), since I loooove the galaxy franchise (100%ed the 2nd game and almost the 1st one too, I will resume it after I finish some exams this month...), and I'd like to see a Pokemon Echlipse title (Not Pokemon Stars. The sun IS a star genius! Gosh Nintendo you would mess it up if you release Stars ...). It doesn't have to be a sequel to Sun and Moon, it can be like a 3rd special game (just like how Pokemon Emerald was for Ruby and Sapphire, Crystal for Gold and Silver, and Platinum for Diamond and Pearl), but I doubt they will make a 3rd game since the last one was Platinum which was 8 years ago... Considering many people thought of a Pokemon Grey title, or even Pokemon Z (I was part of Z lol), so yeah.

greenluigi : There are always games that some of us think need a sequel or a decent remake. And I do not mean CoD it to death,but make meaningful upgrades. And sometimes a remake has to learn KISS or Keep It Simple Stupid. Remember what made it great and go from there. I would like to see a remake of Sunset Riders or X-Men,the arcade game.

Sunset Riders was done by Konami and is a bit like their hit TMNT,except you were a cowboy and had to shoot your way through a level,although it did get harder with new things to master like jumping obstacles while on horseback. Tip: Use the guy on the end,dressed in a sombrero,the shotgun was nice.

X-Men,I think was also done by Konami. If you are lucky enough to play the 6 player version an have a few friends helping you,it is awesome. It is basically,you have to stop Magneto and his goons from destroying the world. You fight through Sentinels and other mutants and stage hazards and it is just pure fun.

Please,dear God,try to keep what was fun about them intact. We do not need more complicated  setups or necessary goals,just let us whoop some digital @$$.

 

So many to choose but may as well list a few.

Star Wars Republic Commando: Without spoiling the game,it ended on a bit of a cliffhanger and had a couple loose ends that needed to be tied.

Comix Zone: Played it to death and would love to see it make a return

I-Ninja: Very underrated title from the 6th gen that was one of my favorites from that gen.

Perfect Dark: Loved this game and even enjoyed the prequel PD Zero on the 360.

 

PaRappa The Rapper.
There hasn't been any new additions besides remasters since 2001... at least I can look at the remasters that don't even add anything to the game...

We definitely need a sequel for Trauma Team on the Wii, that game is an underrated gem, shame it was only released in the USA!

Here are a few that come to mind:
Gemini: Heroes Reborn. Awesome game. Who cares if the show tanked? Don't end the games too!

Harvest Moon: Back To Nature. There have been tons of Harvest Moon games since then, but that game needed a sequel, or at least an Alternate Universe setting of it.

Innocent Life: A Fantasy Harvest Moon. Another HM that needs a sequel.

The Legend of Zelda: The Twilight Princess. This game says all that needs to be said for it.

Future Cop L.A.P.D. One of the best games on PlayStation (PSX), but it was so overlooked. The Precinct Mode made that game. I mean it had a story mode too, but who cared about that? Precinct Mode...now THAT was a game.

Freedom Wars. One of the best games I've ever played. Seriously, why no sequel, or at least spiritual successor from it's developers?

Dragon Quest Builders. Make it happen, guys. And this time add multiplayer.

Final Exam. A good game that did what it did very well, but it could use a sequel that really polishes up the gameplay and improves where the first didn't quite get it right. The first was still a lot of fun though, especially with two players.

Xeodrifter. Awesome indie platformer that could really do with a sequel.

Foul Play. This may be the best beat 'em up ever. Anyone that likes the genre and has a system that can run this game needs to try it.

I could list more, but I'll stop here...and maybe say Bushido Blade 2, and a real Dino Crisis 2 sequel, if we can suggest a sequel for a sequel here.
