DS Slot: Super Robot Taisen W

GBA Slot: Super Robot Taisen Original Generation 2

Super Robot Taisen W.

The Phoenix Wright series is my second favorite series for the DS.

for DS: Super Robot Taisen W (J) is a great strategy game though its easy.

for GBA: Fire Emblem series, Shining Force 1 Remake, and the Super Robot Taisen Series (OG,OG2,A,J,D,R).

Playing Pokemon Diamond: about 4 to 5 hours a day

Playing Super Robot Taisen W: about 6 hours a day

Playing Phoenix Wright: Ace Attorney: 5 to 6 hours a day

It kind of died out after two hours

 Super Robot Wars Alpha 3

I can't rate that collection myself, since I haven't played most of them except for Dragon Quest 8 which I'd say was pretty good.

The best games that I've played in my collection are mostly RPGs
