Perfect Dark

Rollercoaster Tycoon was good too.

Burnout 2

Elite. In terms of scope and content for the time it dwarfs anything else IMHO.

It's WTF and Lemmings. The latter one is a real classic

OT: Dungeon Keeper 2

Given that one of the above posters had never heard of Lemmings I think we may be Veteran Gamers.

The chances are Elite has never been played by most on these forums.

First Open Ended Story I believe

fable 2, GTA4, little big planet

Ah, we can't help being more knowledgeable I guess... this is just like seeing lists for films and music that don't go back further than 4 or 5 years.

Scary to think the time I put into actually getting to Elite!

GTA4, but i had no idea it was a British game.

Fable II

The PS2 GTAs, Black and White, Populous: The Beginning and LittleBigPlanet are among my favourites.
