My biggest gripe is that the game industry seems to have forgotten the fundamentals of gaming. People may take issue with it, but at least my perception is that about 70-80% of a game's budget seems to be dedicated to graphics, and then whatever's left over is spent trying to slap something barely playable together. There are plenty of games from the NES/SNES/Genesis days that are still more fun to play than some game with a couple million dollar budget today.
Then a sub-gripe on this, or at least an associated one, is that then the game companies refuse to acknowledge this very simple and fundamental truth. They will point the finger everywhere but at themselves, and pull stupid movies like tacking on DRM, which just exacerbates the issue rather than addressing it. It's been shown time and time again that piracy actually DRIVES sales, and people who pirate are often some of the biggest spenders.
So I would like to see game companies go back to the days where graphics were secondary to gameplay, and to stop trying to reduce everything to a reproducible formula. I get that it's a business and the aim is to make money, so I don't begrudge a little milking of established franchises, but set aside some money for some more experimental games. Games which may not be huge sellers, but might appeal to a number of people.
