What game can't you put down?

There is absolutely 2 games that hold my attention at this time. I realized this is usually the case if I have time for games that is. I just wanted to know if you guys had anything you just can't put down.

The 2 on my mind right now are:
BlazBlue - one of the best fighters I've played in a long time. It was made by the same people who created the Guilty Gear series. I'm actually building my own arcade stick at the moment, because of this game.

Katamari Forever - Sure for being a NEW katamari game, it's not exactly new. Out of the entire game there is only 4 new stages, but hey when you get to revisit all your favorites from the past games in true HD it can be fun. Also the new moves and modes help the game along. Prince can jump and the infamous Katamari Drive is just amazing. Your katamari goes almost three times as fast as usual, making some maps more difficult such as the race, and turning others into a challenge to collect EVERYTHING on the stage.

i don't play games too often but when I'm in the middle of a GBA Fire Emblem its impossible to put it down.. especially Fire Emblem 7 . ...if it counts, i used to play ddr until i couldn't stand up anymore XD ..though i wasn't too into the lastest ps2 version.. x.x

I used to play DDR until I couldn't stand up as well. I haven't played DDR as much as I used to anymore, so now I'm not as greta as I used to be, but I can still play 90% of the songs on Heavy. I never really played it on console that much, except for Extreme 1. They had Supernova at the mall and then Extreme in an arcade by me. Also, up on the college campus they have DDRX, for free, but only one has a true fully working pad, the others aren't sensitive enough.

RF online. Love the storyline of the game. It's a sci-fi yet a classic
fantasy. It emphasizes the three-way Race vs. Race vs. Race with
modern/futuristic technology such as mecha and nuclear weapons.
But I would appreciate suggestions for other great games that I
should try out.

Really love this kind of games.
