What I watch:
-8-Bit ROB (wish he still did reviews) - Old school reviews done in character by Rob the Robot, with a bit of humor.
-Classic Game Room - Mark was one of the first, and still one of the most reliable online reviewers out there that stays true to his own tastes and views.
-CGR Undertow - A spin-off of Classic Game Room featuring other, newer reviewers other than Mark. My favorite being Derek (can't stand the PC guy with the glasses and pony-tail, though). It's great to get new reviews everyday, thanks to these guys. Discovered so many games here.
-G4 Icons - Re-runs of the single-best show G4 ever produced with a documentary-style reflecting on different subjects throughout the history of gaming.
-Game Sack - Great show that is obviously a labor of love from two old-school gamers. One guy being the Nintendo guy, and the other being the Sega guy. A full half-hour show, too.
-Irate Gamer - I like his tongue-in-cheek style, and various references to other stuff in geek-culture. I also like the recurring side-characters. I know I'm in the minority on him, though. I'm not sure he makes regular reviews anymore, though (those were the only ones I'd watch, none of his "Irate the 80s" or action figure stuff).
-MetalJesusRocks - I like his reviews because he's honest, and he just seems like a cool guy I'd hang-out with if I knew him personally.
-TurboViews - Very professional looking and sounding reviews that focus solely on TurboGrafx-16 and Turbo-CD games. His review releases have slowed to a craw, though, unfortunately.
