Gaming Games that don't take too long to complete?

[War]

I've been trying to catch up on DS games, but it seems like the games I start always take a lot of time to complete (Professor Layton took me 15 hours...) Are there any good games that don't take too long to complete? For me a long time is around 10 hours, so if there's some popular games that take less than 10 hours to complete let me know!

I have played some of the popular ones though. You can check to see what I've already played here.

I was thinking of playing an RPG, but I hear that FFIII/DQIV/DQV/DQMJ take like 20 hours+ to finish...

I've been playing giana sisters it's pretty good. Gameplay can get repetitve but levels are short. Not much story and I haven't seen any new bosses. It's always the old boss but takes more hits to kill and has more attacks. I really like the game though and it goes by quick. It's a platformer.

Thanks for the recommendation, I've been meaning to give that one a try.
