What is your favourite game of all time?

[Max Veteran]

Max Payne 1. Brilliant storyline - the whole game had this whole bleak underworld thing going on which made it very atmospheric - especially when shooting thugs in gritty run down areas of town. I think I'm going to install it again and play it through for about the 6th or 7th time.

The original Unreal Tournament. It was what popped my online gaming cherry. :p

[UKer]

For me it was Sensible World of Soccer - I spent much of the 90s totally hooked on this. A close second is the Monkey Island series - second because it was great fun to play on your own, but as a kid I always played games with friends and SWOS was great for having tournaments with friends and colleagues, and third was Speedball 2 - which again took a great deal of my time in the 90s playing tournaments with friends.

These days I never get the chance to play games like I used to because of other commitments (I'm lucky to get 2-3 hours per week, as you can tell from my gamerscore on XBox!). I think WoW is lightyears ahead of other games, I've come to really enjoy the Pro Evolution series and I've really got to like Fable 2 and Fallout 3 recently, although many games seem too similar and innovation doesn't seem to be in the developers minds when making new games any more - they just seem to churn out more of the same.

[NikkiRox]

doom and portal.

[LOC Veteran]

The original Tetris for me, along with the original King's Quest.

Honorable mentions include NARC, Mercs, the original Wrestlemania arcade cabinet, Silent Scope (come on next gen remake!) and Street Fighter 2 Turbo Edition.
