"PSO, SoA, LoZ:WW, AC, FF:CC, ToP, BK and
GS:LA, AW etc through the GBplayer"
Have to disagree,
PSO isn't to bad but it's only has Multiplayer action. The single player mode is a bit stale (yeah I kinda realize it's meant to be online but still, some tweaks in the single player could have helped).
LoZ: WW isn't an RPG. It's more of an action/adventure with a trance of RPG elements but not close to enough.
AC: LOL, nintendo places this back as a RPG but since it's basically same as EA's Sims, wouldn't be a "Life" or alter life simulator?
ToP? Think you mean ToS

. Yeah this one is actually shaping up real good (received 9.7, 9.5, 9.0, and one 8 from the four top japanese reviewers). Kinda sad you'll still going have to wait (unless you can read japanese), until March+ 2004 for the US and most likely later for Europe.
FFCC recieved mixed reviews, it's basically the same as PSO but think Squaresoft's Game Design Studio should have added a better plot and included some sort of online or at least Friendly AI help.
BK, I take it you're talking about Nacmo's newest RPG, there's not alot to go on for this. It could be a flop or it could be a hit. Won't know for awhile.
That leaves the GBP games.
GS & it's expansion GS LA are good enough but AW? Advance Wars is a strategy game, basically Starcraft clone type.
I really can't call that a positive otherwise you'll have to count the PS2 backwards comp as positive as well. It's not really because A.) most fans have a PS1 just don't bother hooking it up since PS2 can do both, B.) even if you didn't have one you could get them fairly cheap.
Same with the GBA/GBP games. I know alot of PS2 gamers who actually have GBA's so why would they need a GC to play them

.
So right now, there's quite a few quality RPGs that I can play on the PS2 vrs the GC as of now.
What would a hardcore RPG do? Wait two years+, or just buy an PS2?
