Its typically on a game to game basis and usually the problems are related more to smaller/less popular games where the loss to the developer is felt deeper than a massive developer like those who make Battlefield, COD, GTA, etc. Yes, occasionally they will run into issues with specific developers. Note that I've never pre-ordered from one, but after release I've bought plenty of times from these places and never had an issue. I've also purchased many games from various ones and I've NEVER had a problem.
