Not bad...

Thanks, that's a relief...

Let me see... Mega Man games seem to be getting harder with time. Stuff I've played in the series:

Mega Man Anniversary Collection (I've also played the NES versions of a few of these, but not finished them on NES)
Mega Man - completed
Mega Man 2 - completed
Mega Man 3 - completed
Mega Man 4 - completed
Mega Man 5 - completed
Mega Man 6 - completed
Mega Man 7 - got to Wily's Fortress, haven't finished it
Mega Man 8 - got to first stage of Wily's Fortress, gave up because of very high and frusterating difficulty (the stage with the jet-skateboard thing and the spider-ish boss).

GB
Mega Man in Dr. Wily's Revenge - completed
Mega Man II - completed
Mega Man IV - completed

PC
Mega Man 3 (Hi Tech Expressions, not Capcom, not very good) - unfinished - no saving
Mega Man X - got to final Sigma, didn't finish. Got all powerups/items.
Mega Man X4 - completed
Mega Man X5 - got to Black Demon boss, gave up because it's impossible

SNES
Mega Man X - same as PC version.

PSX
Mega Man X6 - just started, I don't see much hope of progress...

GBA
Mega Man & Bass - got only a little while into the game before giving up because of very high difficulty

... and I haven't played the MM Zero/MM ZX games much, but I've heard they're quite hard too...
