Goldeneye has got so many, absolutely, awesome memories for me... thats by playing it in probably the peak of my teenage years 16/17 or so, with mates, with drink etc
Sometimes it would be serious, othertimes just so hilarious that id be in tears of laughter trying to play. I doubt anyone would remember this or find it that funny but remember this was the first game of its kind (pretty much anyway) amd being able to 'slide' around on your knees was funny... especially if you were hiding behind a wall then your opponent just skied by on his knees.. oh I can remember it now, we just p'ed ourselves when it came on the tv.
Anyway apart from that, because it holds so many singleplayer and local MP moments.. the game that probably defined a lot for me was MOHAA. MY first real PC FPS in the sense that I played it online... now the SP had its moments, I think the first level being like Private Ryan was pretty nuts for its day, but its MP is where it stood out.
Im not exagerating here when I say at its peak and it had a pretty big peak, the game could have been as big as CS or at least a very big no.2. Now you might think im crazy but that game was so slick to play, the movement, the maps, the weapons.. it just flowed and it came down to skill and aim. No gimmicks, just pick a weapon which each team had its equivalent and get on the map and do your biz.
Sadly the game lacked support as I believe the devs left EA and most of them ended up doing COD1....but with proper support ie Anti Cheat, patches, map fixes, proper add ons that didnt change the gameplay.. then MOHAA could easily be very much alive today.
Im waffling as the game holds so many memories that ill never, ever, match again and that makes me sad.
