This isn't much of an issue, but I can think of several different reasons why the white character is the standard:
1) The majority of game makers right now are likely white males. They want to make their characters believable, so in order to do that they stick to making characters that they can identify with, and therefore craft better personalities for. This could also explain the stereoypes, though in some cases (Gears Of War/Saint's Row) you can sense that the developers were taking a dig at the stereotypes that they were including.
2) The game makers think that white main characters sell games. Remember, regardless of how fun they are, games are a buisness, and that means that they're there to sell you a product. It might just be that the makers decided that white characters tend to to sell more games, in which case they're only giving us what we've indicated we want. Bad games/unprofitable games lose money: in fact, most games lose money, so the developers are less inclined to take risks in their games because they don't want to rock the boat. This is why you see swarms of sequels instead of new IPs all the time: devs need titles that they know will sell in order to finance the rest of their games.
3) The game makers are, ironically, scared of the possibility of being called racists. Ethnic arguments can easily erupt over games: remember Resident Evil 5 (admittedly deserved)? Any sort of negative coverage erupting over a game has a significant chance of losing them sales: and accusations of racism in their games could easily hurt their bottom line. This would be the same reason sex in games is uncommon: if the game makers include sex, they gain publicity: but a lot of it is negative publicity from the media.
These are all just theories of course.
