I would take a cross-platform flight simulator as the biggest offense ever. Something along the lines of the developer saying "The PC has lost it for us, we'll only do console stuff now. You PC guys will get a half-arsed port, if you really need our product".
No, thank you.
That is my point, I have nothing against consoles, I own a PS2 and an Xbox360 and if you are into gaming, they are a blast, BUT from my experience, design studios usually don't or won't have the resources to FULLY develop dedicated versions for both platforms, so one suffers, either you get a version for the console that was designed for the PC that doesn't play right /too hard, or you get a dumbed down PC version. So my solution for that is to support one version or the other and show my support to the game makers with my wallet since that is what motivates them, sales.
I choose the PC and don't buy consoles or console games any more. You realize how many PC games I have that I haven't played/ can't play on my rig that I bought just to support PC gaming? (fallout 3 and far cry 2 keep staring me in the face!)
What's really sad is I was at gamespot online the other day looking at the release of SIMS3 and reading the comments from the kiddie gamers and most of them is "why can't I play this on my WWii, PS3, Xbox360, etc, WAAAHH", they just don't have a clue.
What I do find interesting is that consoles, are getting bigger and faster, basically becoming computer spec quality, so why have dual platforms? Is it because you have a harder time cracking code on a console?
