As in games you feel could’ve been better.

I’d have to choose Geist.

Since that game had a brilliant concept, of possessing objects and people, in order to progress; that unfortunately was poorly implemented with a bad game engine, and was sometimes hard to figure out how to proceed. Which is a shame, since the game was so original otherwise.

Have any additional games to list?

I will just leave this here 

Geist came out on the wrong console. It was a mistake to release a game aimed at teens for a console aimed at children.

MAG !!!!!!

yep, great potiential, poorly executed which seem to be an problem with Zipper at the moment, they have poorly executed Socom there prestige franchise and i dont see them doing well. 

Alan Wake for me... Not saying it is an bad game but it is sad that it ended up so linear while it would have been an sandbox game,  the idea of Alan wake being in an open world setting..Well I would have loved that :).

Anything from Peter Molyneux. 

I remember him talking about the first Fable and thinking it will change gaming. It's a shame he barely ever even gets close to the potential he clamis his games have.

Bully.

There's just so much that can be done with the game.

Not to mention being less gun-ho and more atmospheric and creepy.

Hey, the first Magic Carpet and Syndicate were cool games.

And Theme Park and Dungeon Keeper.
