Someone needs to do a comprehensive article about all of the Batman video games. And a video games section of the site would be pretty bitchin', Paul. I volunteer to bulk up any such possible section any way I can, should you like the idea. I personally would love to work on/read a comprehensive catalogue of all Batman games. He's had a lot, and so many of them good/excellent. More than people think.
Old post, yet encouraging, there's at least one more person that thinks Batman games didn't suck before Arkham Asylum came along.
(edit dated June 9)
I wanted to do a proper retrospective on those games, at least the good ones, similar to the format employed by http://www.hardcoregaming101.net/
, one of the definitive retro gaming sites.
They've already done extensive articles about games that are very loosely connected together (different developers, systems, gaming generations etc) and have only the licence as the common core (e.g Asterix, Donald Duck). Their style is very informative and is more about facts about the games, when known, as well as explaining and describing how each game works, and less about expressing the personal opinion of the writers.
However, something like this takes a lot of time and research, and I don't think it's worth it.
