Whoa a new Top 5! Let start now =p!
#5: Pokemon Diamond/Pearl: This game get the #5 spot because Pokemon is pretty much the leader of Portable gaming. Pokemon on the DS is the best thing that has happen to the DS! With Wi-Fi Trading and Battling, over 400+ Pokemon, good challenges, and over 40+ Hours of gaming. ~I Have put over 500 hours but thats just me.~ This game is perfect!
#4: Mario & Luigi: PiT: This got the #4 spot because this is a great RPG for the DS. Lots of area to explore, new enemies, items, and partners. But it could have gotten Wi-Fi to battle other people. I think that would have been great. This game has great boss battles and loads of comedy!
#3: Mario Kart DS: Of course, Mario Kart DS is a must! Bring the new stuff with the old stuff to make this great game. A good variety of characters, courses, and items makes this game fun. With Single and Multi card games, and Wi-Fi races ~which are usually bad thanks to Snakers~ this game is great!
#2: Mario & Luigi: SS: This game is better then the second one! The first Mario & Luigi is funnier, and just funner overall. The Bros. Moves were probably the best addition to this game. But a good world to explore, very good storyline, and challenging boss battles makes this one of the REALLY GOOD RPG for the portable systems.
~Try to guess this~
#1: Pokemon Red/Blue/Yellow: Of course, the retro Pokemon is the best. You cant say it isnt. Eveyrone got INTO this game. It was #1 in the 90's and #1 still now. I rather play this game then any other game on a portable stuff. I still has that "Still feels new" feel.
