psp ..Wipeout = win

Looking at the list, I had an Gameboy, Game advance and game boy SP all for one game Pokemon and none of them had it as an launch title. 

PSP titles appeal more to me. tho Tetris was revolutionary in the gaming market when it went portable.Could say it started the causal gamer market. 

Retrospectively GB just because of Tetris, one of the most important, influential and successful games ever.

Subjectively: GBA and PSP.

I thought that launch games were always awful - I didn't realise how awesome the GBA's was, haha

I think it's funny that people seem to doom 3DS because of it's less than impressive launch line-up, but looking at this list and the list for consoles it is in good company. My choice is either GB for Super Mario Land, GBA for Castlevania or 3DS for Street Fighter

Game Boy for sure, and it seems that launch line ups have been getting weaker and weaker ever since, which I just can't understand.

Gameboy

Best puzzle game ever. Check

Game staring biggest video game icon check

I dont expect a great puzzle game at a Ninty system lauch, but I do expect a good Mario game. Ive yet to buy a Ninty system before a Mario was out. Im actually becoming stricter and probably wont buy another Ninty system without a 2Dmario.

nobody wins cause they all blow, really unless you just play portable exclusively and dont touch consoles all of most of those titles are underwhelming as they are ports of games that were already available on consoles at least the games i would play anyway.  GBA>3DS=/=PSP icant decide between the two

Well that was easy...

for me is GBA > PSP > 3DS > DS > everything else.

looking back DS launch library was really weak (but i think you missed some games, i remember picking up 3 games with the ds, and they were sm64, feel the magic and ridge racer... i remember well because i live in europe and since i couldn't wait i imported my ds from usa)
