20. Fallout 3 (PC, also on 360 & PS3)
Fallout 1 & 2 were classic old-school RPGs. Fallout 3 is Oblivion with guns! When I found out Bethesda were doing the new game I was very excited and it didn't dissappoint. Large open sprawling world, the perks that made the original games great and an odd mix of old school Fallout atmosphere mixed with modern open-world Oblivion-esque gameplay. It just seemed to have a great mix of old and new WRPG elements. Nearly all of my gamer points are thanks to this game (A full 1500 thanks to the DLC!). The levelling system was great and exploring the each new area was actually a joy. The lessons learnt on Fallout 3 (and Oblivion for that matter) have also translated well into the new elder scrolls game Skyrim.
