Dunno if I'm eloquent enough to properly praise it but here goes...
Talking about Batman Asylum, it just did everything so well. The atmosphere, the voices, the story, the setting, the gameplay. Everything was crafted with love and attention and If you like me, grew up with the cartoon, you can't help but feel it was a special game. I know it all sounds a bit vague perhaps. It was my favourite superhero game until Spider-Man on the ps4 (that I kind of accidentally played and totally fell in love with) but I genuinely think that there are no other superhero games that did it as well as Arkham Asylum and Arkham City.
If the big boys would put out games today that were crafted with this much attention, then they wouldn't be in the straits they're in now.
