It's nice you have an opinion, KOM.Nausicaa. Unfortunately not every mac user shares it. Friend of mine is a music producer and is forced to use macs due to certain software restrictions. He hates them and every spare minute he uses the PC instead.
Personally I haven't seen a single just motive to switch to mac if the PC is used
properly. I switched to Win 7-64 recently out of curiosity, not because my Win XP was lacking (and I'm a heavy user). But maybe that's a difference between an artist and a tech junkie, I solve problems or choose a workaround instead of running away from them (wait 'till your mac breaks down, I've seen plenty dead or crippled macs with angry or horrified users, believe me). On the other hand, build a PC based on an Asus motherboard, choose a quality harddisk and install a multiboot with NT based OSses, keep your airflow proper and there is no reason for your PC to have
any downtime.
About cross platform titles:
Bad idea. I saw the differences between titles in the eighties and early nineties between platforms: Amiga, Atari ST, C64, C128, PC.... Instead of having one title that was developed to the max, there was a division of resources. I've seen a lot of bugs and lacking performance.
I want 1C to use
all their resources for improving the product, not to boldly go into wild adventures into unknown territory. The aim is to make the best simulation, period. Not the best selling but average simulation.
