I've got faaaar too many on the go atm...
DS :
Final Fantasy III
Final Fantasy V
Haven't yet finished either due to laziness. Add to this I'm recieving IV & VI Advance tomorrow, both of which will require a play through (despite having been completed on other formats). VI will definitely be started tomorrow...
PS3 :
I'm yet to finish
Resistance & Motorstorm, both of which I got on release day, both of which I still thoroughly enjoy.
R6V - I'm stuck at the beginning of the Dam.
Kula World - Evil evil Kula World. Currently at level 80-odd.
Tekken 5 - I just want to play enough so that I can beat RP2000 and NumberOneDon EVERY time, rather than every other time
COD4 - Currently at level 31...
Warhawk - More time needed here too.
Oblivion - I've finished the main campaign and most of the side quests, I just want a UK release of Shivering Isles.
Marvel Ultimate Alliance - A very fun (but flawed) game, that I really ought to put the hours into (I LOVE Marvel

)
PS2 :
My progress in
Final Fantasy XII halted the second that my PS3 arrived... I might transfer the saves one day, or just start again!
Then there's the fact that I want to replay Final Fantasy VIII at some point, though I'm making sure I don't do it until I've got a PocketStation... Incidentally, does anyone here have a PocketStation and FFVIII? It's the only way to get 100% completion
THEN there's the fact that I've several Japanese version Final Fantasys that I intend to play through to learn Japanese! I need a Famicom first though!
I've probably forgotten a number of things here, and I haven't mentioned the PC RPGs....
*phew*
