It seems like a few of us are enjoying Arkham City, so I thought to throw this one into the mix. In days gone by I loved Batman Returns on the SNES, and had a decent time with Shattered Dimensions on the Wii. It was somewhat buggy but hearing all four Spider-Men saying the same lines was surprisingly cool (not being sarcastic!). My favourite, though, was the original Spider-Man game on the PlayStation. The first time I felt the genuine thrill of being a superhero, which runs right throughout Arkham City.
Over to you!
