Well, I REALLY LIKE THE WHOLE GAME!!! ALL OF IT!!!
Sure there's always room for improvement, but hey they'll put updates to the game!
I find this my personal best in the genre off-road games! (I did played and liked Screamer 4x4 as wel! I have the torrent if you like

) For me this game gives me the same thrill as Anno 1404 Venice is for the best RTS.
And yes a free world to drive would be very nice

Or where you can build your own world with obstacles and stuff... (or at least like the pathfinder option in Screamer)
And you should be able to buy (way more) upgrades (and vehicules) and not just adjust them...
There should be a V-Sync option (that works) --> I'm currently busy in an other thread with the V-Sync stuff...
And an annoying bug is occuring sometimes: When driving with the keyboard it sometimes stops and shows the same menu when you hit the ESC-key... Ok just pressing Resume would do fine, but its annoying when your in a corner :p
Racing it with the MOMO did not result in this bug... (Maybe its a press-too-much-keys-at-once-bug)
No really in general this game "ROCKS"
I'm gonna e-mail the developers because when I was like 8 years old I played Street Rod (on Commodore Amiga 500, not the PC version--> that sucked) and was sooooooooo addicted to the game that from then on I start typing in Workbench's Text Editor (can't recall the name :p and Workbench was Amiga's "Windows" but better. :p) a whole game that I would like! And that game was like Street Rod, but then with Off-Road cars... (Hell I even have it printed out on my Star LC-200 printer on chain-paper... Haaaa memories...)
I even retypt it in a Word-file how it should look like, and wich options it would have and all the details. Really ALL the details... At age of 8
Oh yeah, why was I gonna e-mail the developers? To give them my idea of the NEXT game they will develop :p --> Remember my name as ASUSfreak WILL be part of Off-Road Drive 2 :p!!! (Because now (8y + 23y later) somebody FINNALY makes a game with the detail I had at age 8!!!
I know, I know, I'm a genious

but I'm a hardware freak and not a software dude... (else I build the game a long time ago

)
Yeah well, I think you'll know now that I like this game
Hey OP you asked for it
