3 day lag time double post??
I debated on getting a DS, and then when I was looking at games on eBay and saw a new version of CT, that pretty much sealed it for me. Got a nice DSL. Unfortunately, I'm waiting for another copy of CTDS, as the first one I got was a cheap China ripoff that corrupted save files. But eBay got me my money back, so I'm not too irritated. Before the save files become completely f*ed up, I was able to play a decent bit and got to right before Tyranno Lair (love the DS sleep mode). I thought the arena was pretty cool, kinda like a CT themed pokemon.
Other DS games I have: Tetris, Ninja Gaiden, and Star Wars: The Force Unleashed. Tetris is good if you like other versions of it. There's some new game types that add to playability. Ninja Gaiden, I haven't gotten too far into, but it's similar in graphics to the Xbox version (NG, not NG2), but slightly dumbed down for the DS. Controls, almost entirely through the touchpad, are kinda difficult to get. Force Unleashed is very straight forward and lacking in challenge (you can't walk off ledges; many battled can be won by just spamming the lightsabre button). If your a Star Wars fan, I'd go for the game on another system.
I've also got a DSTT card coming so I can use my DS with homebrew organizer apps and such.
