I noticed on other forums gamers complained about having to install DMC4 on PS3 HDD so most console gamers like everything to be very simple.
This is probably why there were more hardcore games on the PS than on PS2 and now the Wii is out selling both the ps3 and 360 combined. (Even many years ago (back in C-64) I found most console games were more simplifed including hardcore games like Silent Service.) I find that even some recent PC games seem to be dumb down a bit lately.
P.S. Both Civ1 and Civ2 were ported straight to consoles yet they didn't sale very well. Starcraft was also on the consoles (N64) yet never sold anywhere close to the PC version.
I'm ok with you using the SNES version of Civ as an example, but not starcraft or C&C for N64 because there was no mouse for that console and thereby the game was close to unplayable. I know because I own them both. Its like controlling 1 unit at a time all the time. So those prob sold bad mostly because you couldnt play with a good controller. C&C also had nice 3d graphics
