Hello, perhaps you would like to consider Gambitious to be your crowdfunding platform, rather similar to KickStarter as it would appear, although less well known, and focusing only on video games. Firefly studios who are developing Stronghold Crusader 2 a castle builder RTS have chosen it as their funding platform, and have a large following there. They have already brought alot of the focus group you want to the site, imo this is why it's the best candidate. I don't know about the finer details: bank account locale conditions, etc. Have a look if your interested. You can offer perks as further incentives for pledgers/investors, though they say the perks must be offered as an additional project...i may be incorrect.
