I think that a lot of games will come with their own altcoin, because it's way easier to govern their economy that way. It's not smart to use bitcoin because that will mean loads of users will become rich/poor from one day to the other.
That is not true at all. I am not sure how can you say that using their own alt will be better? It won't be better at all. And imagine situation where every game with F2P model creates their own currency - only compatible with shop in said game and can't be used outside it at all. This one hell of a stupid idea.
How is it stupid? Blizzard could create BlizzCoin, valve could create ValveCoin or something to use in their F2P games like DOTA and TF2. It's not a stupid idea at all. Yes, for an end user to make profit from something like this would be hard, but that's not the point.
You say it's stupid but you don't give any reasons for it. That's not participating in a discussion, maku.
