Earth worm Jim on the Megadrive, all my mates were like "its awesome" so i tried it and it just didnt appeal. Just felt like rayman as a worm, now im not sure which came first, rayman or Earthworm jim but i enjoy rayman and nothing will take its place!

For me i think it was Sonic an Knuckles

Me and my bro got loads of hours clocked for this, too bad we dont play it anymore :\

I could not order them 1 to 5 but here they are in no particular order;

Metal Gear Solid

Tropico

Stronghold

Megaman 2

Civilization IV
