Well, here are my fifteen favourite games of all time for anyone that cares (1 being the best and 15 the 'worst')
15) KILLZONE (PS2)
This game gave me many hours of fun gameplay both online and offline; I know it wasn't the highest rated game of all time, but at the time for me it was extremely fun.
14) HALO 3 (X360)
If this needs a description then you really shouldn't be here. Doesn't have a huge amount of replay value so not so high in the list.
13) MEDAL OF HONOUR: ALLIED ASSAULT (PC)
This is the first proper pc game that I ever played alot; and one of the first online games I played. It was ok, and considering at the time I only had 56k, pretty amazing that I could even play it.
12) CRASH BANDICOOT (PS1)
One of the best playstation one games out there; ridicously original and amazingly fun (whilst being frustratingly hard at the same time).
11) MX UNLEASHED (PS2)
This game, I found out was actually a limited edition and I'm really annoyed that I traded it in . It was really fun, and pretty realistic in some places. Highly reccomended if you can find it anywhere.
10) QUAKE 3 (PC)
Anyone who's ever played this will definitely agree with me. A game that was well ahead of its time and an instant ****c for LAN parties.
9) ARMOURED CORE (PS1)
This must be one of the first games I ever played. I never actually even had the game; I just played the demo that came with the playstation to death.
8 ) VIGILANTE 8 (PS1)
Obviously this had to be inhere somewhere (appropriately in slot 8 ), I'd probably still be playing this to this day if I hadn't lost the disc.
7) GTA: VICE CITY (PS2)
This doesn't really need to be explained except to say that it is clearly the best GTA game, because it's the most original and it doesn't have hundreds of features that are never used and that are just plain annoying.
6) CALL OF DUTY 4: MODERN WARFARE (X360)
An amazing game that combines a number of different techniques that both work, and work well. AlsoI'd like to add that it has most definitely the best singleplayer campaign I've ever played.
5) RED ALERT 2 (PC)
In my opinion the best of the Command and Conquer games so far closely rivalled by Tiberium Sun. Huge amounts of fun and replay value. Campaigns were hard, but very very satisfying.
4) RED FACTION (PS2)
If you have never played this (the sequel does not count) you have to go out today and buy it. This game was doing things that most games have only just started to do as a requirement for todays standards.
3) TIMESPLITTERS: FUTURE PERFECT (PS2)
Fantastic game; the singleplayer was exhillerating, the multiplayer was the most fun I've ever had (not including the online play) and none of that includes the two best features; the map maker and the arcade games (from which I won an Official Playstation Magazine competition).
2) GEARS OF WAR (X360)
I honestly do not need a reason for why this is No. 2 on my list; obviously apart from No.1, it's the best online game ever. Which, combined with the incredible co-op campaign and the insense graphics and sound effects makes it the game it is today with the most anticipated sequel of 2008.
1) SOCOM 3 (PS2)
Admitidly, the singleplayer for socom 3 was not great; but the multiplayer was what everyone played it for anyway. I made some friends on there that I'll probably keep for a very long time. Not only was the game a ton of fun, it was quite realistic, required skill (in most parts) and the community was epic. I had some of the best times of my life playing socom and it was without a doubt the best period of my life so far, so care-free and fun. This is why I can't wait for Socom Confrontation (which I'll actually have to buy a ps3 for).
