heres my take on trying the ww2ol demo offline. I tried gettign online but had trouble getting a free trial account activated and didnt feel like bothering with the online part for the moment.
as far as keymapper unfriendliness i had some of that but nothing that wasnt fixable with basic logic and problem solving skills (its not friendly but usable and I would call ww2ol keymapper DOS and AH keymapper WinXP).
but the in game stuff to me is quite kick bellybutton as far as detail and intuitive use goes...
tanks:
the tanks function about like AH tanks (driver, gunner, commander) but can only be steered while driving. but these tanks have all the features i wish AH tanks had (button,unbotton hatches, actual crew member modelling, real gunsight zoom capability modeling etc etc)
planes:
(I'm a pilot, Ive flown t6 texan too so ive flown a warbird sort of

) AH flight modelling feels more accurate in the low speed stall range and ah is far from perfect too. but the planes in ww2ol though marvelous in normal flight envelope with superior sense of traveling through air (ah feels like its on rails) suffers in the E retention and stall/spin departure department. the one below stall speed maneuver that nehaves more realistic in ww2ol is the hammerhead (in AH wierd things happen when doing a hammerhead) landscape in WW2ol is much better than AH as you dont need GPS and can navigate by landmarks wich any pilot finds a great feature for increasing immersion and realism. view system is standard nonmovable 3d cockpit with no direct 6 view wich i like the no direct linda blair view but AH head movement save view is the true realism way to do a3d view system simulating pilot head movement in cockpit.
didnt try the guns or infantry yet.
not sure if i want to bother with the hassle of dealing with CRS with all the hoops I had to go through just to find a demo ( I already tried buying the game in stores and it was in none)
so they may get one less customer here just for the difficulty they have given the customer (me) in obtaining and using their product in even the simplest online free 1 week trial. is enough hassle learning a new game and dying over and over the added hassle of dealing with hurdle after hurdle in trying to even play this game makes it almost not worth the bother.
