From AHWiki
Aces High II is a massive multi-player online combat simulation centered around the World War II air-war.
The GVs are a wart on an otherwise great flight sim. They pretty much serve the same purpose as power chairs at a Wal-Mart. They're in the way and most people using them don't need them they're just too lazy not to.
Went and looked at AHWiki to check it out. If I'm reading correctly the page where you pulled the quote from was created by a player not a staff member of HTC. I think I'll stay with the front page since I know that it is coming directly from HTC.
As for the GV's being a "wart" to the game, I find them kind of fun when I get bored of flying. My preference is flying, but at times I get bored and GVing is a way to break it up a bit.
Have no idea what you are talking about concerning the "power chairs".
