Yeh, Sorry I forgot you know who I am and what 4x4 experience I have. But that is neither here nor there.
I'm not saying it can,t be done but there are always limitations within games be it physics / graphics / cross platform programing / Disc space / but normally money. Most probably all these combined. But as it goes 40+ tracks bearing mind the time they took on complete on the demo seems perfectly reasonable IMHO.
One case in point (DIRT3) Awesome graphics / great physics / Very limited tracks. 11.2 gigs of space on my hard drive after add-on's CodeMasters Have the money to throw at it. Now I do not know of 1c's financial clout but i wager it's way more limited than CodeMasters. And by that measure from what i have seen 1c has done a pretty fine job all in all.
+If you don't like it don't buy it..But for now it's the best thing going. Fuel was awful by the way. And as good as just cause & gta were totally different, they were sandbox in design and not sim orientated at all. but being clever you should know that.
