Strike CEOs statement isn't applicable as a blanket statement I think. It all depends on game to game, deal to deal, single player or otherwise. For a new company, launching a new game in a new IP is always a risky affair. They would have a projection to move X amount of units, but that's enveloped in a lot of risks. What if the reception isn't as expected? What if players find loads of bugs not addressed by QA? What if word of mouth turns bad? What if the game is well made, but it just gets overlooked Vs competing products? Companies have to weigh that risk Vs the guaranteed payment offered by services like GP. Sure, the game might miss out on some earnings potential, but on the other hand the risk of failure is lower. You get more eyeballs, you get more exposure, the IP gets more exposure.
