It's a real shame that you're looking for the systems and categories you are, becuase they seem to be collectively the least played in my repetoire.
I don't have or want a 3DS, mostly because I found it to be a royal pain in the neck/headache making it nigh unplayable without turning the 3D slider down to minimum. I got a DS at launch and have dozens of games for it, so it's not like I'm anti-DS, I just feel the 3DS was a real misfire and kind of a flop as far as quality is concerned.
my Wii is currently at my Girlfriend's place, and she went away to college so I won't be getting that back any time soon. Plus all the Wii games that I'd want to play are ones everyon else would get to first.
I could do PSN/XBL games, I love getting downloaded stuff a lot, but I find I'm not as knowledgeable about those games compared to the big budgeted games.
I completely lack a gaming PC rig. I was able to play Left 4 Dead 2 and Portal 2 with no issues, but I wouldn't be able to play crysis if my life depended on it.
I'm a little biased against sports games (not a fanboy, I just avoid the genre like the plague)
I like Shooters, but I'm pretty picky, and have quirky opinions on the genre (I felt bulletstorm was an infinitely more fun and enjoyable game than Halo)
I love fighting games but just suck at them, so I don't feel I'd be a good reviewer of them. The same thing goes for Puzzle games and Strategy games (portal being a notable exception)
I like Western RPG's, but most of the good ones (elder Scrolls, Mass Effect, etc) are going to be taken care of by more experienced reviwers.
The more I look back at it, the more I think I may be a little picky, but the truth is I own more games of more varied genres than anyone I know. I have about 50 PS3 games, 25 360 games, 20 Wii games, 25 DS games, and a mere 15 PSP games (working on getting that higher). Regardless, I will happily put in an application to review, I just want to write and do so with purpose, I don't even need money! (I'd be happy to review for games!)
