I'd have to say my favorites would be.

PAC-MAN: It was the best addictive Atari game ever. I know I'm old well my mum's old and rubbed off on me lol.

Sims 2: Because its a cool game but also because they have cheesey little name like "Woohoo".

Final Fantasy: The whole series because it's just awesome.

Halo and Halo 2: Thanks to my bf, and the fact that it was the first FPS that I ever played an loved.

An beat up on Trev: It counts I made it one day when I was bored and frustrated with my brother thats what I get for having a 1 yr old around the house. It's a very cute lil game too amazingly.
