There is already a forum where IBS guys go and chat and post games. I would suggest using this forum except for the fact the guys there are manly newbies thinking they are the best or they are like galli. Try it if you want.
I've taken a look at AC7, and I'm not too impressed with it. As far as I'm concerned air combat is just an attempted rehash of the playstation arcade where the aircraft look like they're just hanging there. Playstation had a chance to do something with this flight sim, but I don't ever see them doing it. At least I haven't. I don't even know if I would play a demo even if AC7 had one.
What I mean is that playstation started out with the split screen Air Combat with the F-16. It had pretty good performance, something like novalogic even though it was limited. Playstation had the chance to carry on from that type of base model but, for some reason, they just trashed it and went to that ridiculous arcade thing they had in PSII or III, or whatever. Anyways, they improved the graphics and added aircraft in their AC7, but it's still the same thing as far as I'm concerned.
