not sure how the fuck anyone investing is expecting anything close to a good return within even 2 or 3 years, and that's especially risky with a game like overwatch which can either maybe grow or maybe continue to shrink once its novelty wears off
it would make much more sense to do this with a game that has a significantly lower chance of wearing off (eg one that already is well established and likely not going anywhere like dota as many have mentioned)
