plus the limit on the number of players in an arena sucks.
150 folks is the max. 99 is about the highest pub server you will see. Some like VP run 64 max. However, pub DF servers usually cap between 36 and 50 players. However, these are set up to concentrate the fights. If the server is running a script then the combat / target areas are usually evenly split between the airfields along the front lines. There are typically just 2 or 3 bases per side and with the average map in FB 1/4 the size of an AH map the flight times are short and the combat concentrated.
Try the Winds of War Server, its a DF pub and caps at 50 players.
Most everyone I know who players both AH2 and FB/AEP/PF gets better performance with more bells and whistles activated in FB/AEP/PF then they get with AH. I not sure what's so hard about the setup in Il2. All you have to do is click on the icon that says 'setup'.
Any tweaking can be done right from the config.ini.
I have played Il2/FB/AEP/PF and AH since both were in beta. I find FB/AEP/PF is far more fun and I play it daily. I only play AH sporadically and mostly just for events.
As for the 'view system' all other games have/had the same view system as Il2. The odd ball is AH. While the AH view system is less restrictive it has its issues. In some planes you move your head out side the glass. If AH is the only flight game you play then I can imagine the difficulty some may have with the views in other flight games. However, if you play enough of them, long enough you adjust and its not much of an issue, especially with TrackIR. BoB will have 6DOF, FB/AEP/PF wont ever 6DOF get due to how they model the cockpits and it would be too much effort to correct them just for 6DOF.
Both games have their features/quirks that make them what they are. AH and FB/AEP/PF aren't in direct competion anyway. Only 10% of those who bought the IL2 series play on line according to Oleg. Any comparison is mostly irrelevant, play the game you like...
The CFS series never did it for me. I quit buying them after CFS2. Some folks like it but IMHO the series sucks arse.
