The systems I own are as follows:
Nintendo (NES): Playing Dragon Warrior II right now, but it's boring. Loved the first one, I need to get thru this to play the others.
Super Nintendo: Just screwing around with different games. Played some Psycho Dream last night, seems like a fun game, almost like an adventure/side-scrolling shooter combo.
N64: Just got a gold one. I'm not playing anything on it tho, and haven't the whole time I've owned one (from the grey one I had before to this one).
Gamecube: Not playing atm.
DS: Playing FF3, which I need to finish so I can work on DQIV. Was playing Tales of Phantasia but I got bored with it.
Sega Master System: Nothing right now. Was playing Ys. I hate Ys.
Sega CDX: Nothing at the moment. Bummed that Dragon Slayer: Legend of Heroes doesn't work with a Game Genie (it's region protected). Was playing Shining Force CD, but didn't check the console first and found out I had no room to save it. XD
Saturn: Nothing right now. Gave up on Albert Odyssey b/c it's pretty bland w/ some of the lamest WD jokes ever. Also, tried to play Princess Maker 2. I need to use a guide tho, as I don't know a lick of Japanese.
Dreamcast: Nothing right now. Was playing Black Matrix (?) or whatever it's called, but that was just to fool around with. I need to finish Shenmue II. XD
Game Gear: Last thing I played was the Oasis game and couldn't figure out how to save. It was fun tho. I just got a Master System converter so I can play Master system games on there. Won't I look cool w/ that + a battery pack on the bus? ROFL!
Playstation: Nothing. I can't seem to hunker down with any game right now. I was playing Tales of Destiny and will likely go back to playing it soon.
PS2: Persona 3: FES, which I play in bursts cuz it's kinda boring. SMT: Nocturne, which I need to get back to. Rule of Rose, which is fun despite it's many many flaws.
PSP: Jeanne D'arc, which pisses me off for how often I need to restart a battle. Also, playing stuff on the emulator. Just finished Radical Dreamers.
X-Box: Nothing. It's worse than useless.
X-Box 360: Eternal Sonata is all kinds of awesome. The battle engine is seriously frustrating tho.
TG-16: Nothing really. Was playing Splatterhouse, but I suck at it. Was playing Neutopia but I lost my codes. XD
PC-Engine CD: Played a bit of Rondo of Blood. I like Castlevania, but I don't play the games b/c I suck at those kinds of games. BTW, is it just me, or do you play as Ryu from Street Fighter in this Castlevania? ROFL.
Wonderswan Color: I have the FF2 box set edition and a bunch of games, but I've only played it a short time. It's more a collector's item, even tho I have a ton of games for it.
Dragon Quest Swordmaster: Ok so it's not a system, but I'm playing it and it's pretty fun, even tho it doesn't work half the time (the sword doesn't show up on screen or blinks on and off).
