My retro collection has had to be trimmed down a huge amount due to lacking space, the few systems I kept are a Sinclair ZX Spectrum, Atari 800XL with SDNuxx drive (purely for Dropzone), my beloved Sega Dreamcast with dual arcade sticks (for Soulcalibur), a Sega Gamecube with dual setup, used for 4 player Pacman Vs and my well worn Playstation 2.
Battlefield 3: Bashball
Planetside 2 (EU Miller) Bashball/Soolin. (EU Cobalt) KinkyDeath
The Secret World - Sylfia (Templar), Funnygirl (Illuminati), PradaDevil (Templar), Kikuya (Dragon)
