No, real flight simming will always be apart of the PC world. Besides LOMAC probably wouldnt run on XBOX, maybe PS3 or XBOX 2, but think about it, flight sims are rooted in the PC gaming world... sports games are not. Something about college students hudled in a dorm room drinking beer and eating pizza while they take turns talking sh*t to eachother over a friendly game of Madden. Now can you see this with a PC??? Sure, it doesnt sound to far fetched until you delve into the psyche of a gamer. You have 3 types, the guy that plays sports and fighting games, and occasionally an FPS or GTA, or a racing game; get the idea of who this person is? He probably isnt too into having to learn how to use a 7 mode Russian weapons system , infact I would be suprised if this average joe even knew what radar was. I have seen it with my own eyes, flight sims are just too hard for regular people to learn. The other type of gamer is the one that is stuck in another world... the RPG gamer... need I say more (not poking at anyone) but spells and goblins aren't my thing. The last type of gamer would be the guy that plays crap that is rooted in some form of reality and or history... Most FPS's and Flight sims, and probably an RTS. Those people are a much smaller group than the 1st group but a larger one than the 2nd. But if you look at the games that the 1st group (average joe) plays, you will see that they make up the overwhelming bulk of games. Just look at all the sports games that are made, and then fighting games, and racing games.
I think the XBOX is capable of running a few sims, but its just not economical for a company to sink money into a genre that is not all that popular. It wouldnt take much to convert the hardware to say an XBOX but think of the risk in converting all that hardware, and if it doesnt pay off, then that company is out a whole lot of money.
Note: I belong to groups 1 and 3 of gamer. But sims are the most fun.
In short, the buying public in general still looks at PC gaming as the "DORK" of gaming; its okay to play on an XBOX but the computer is still for "smart people" even though windows is easy enough for a 3 yr old, and since Sims are attached to a PC stigma... they too are kinda dorkish... but not as fruity as something like D&D online.
Again, please nobody take offence to what I have said. It's just my 2 cents.
Cheers,
