For what it's worth, probably not much, I'd estimate the sales of the original Fallout games to be well over 200,000 in the last few years (going by it has outsold TW2 on GOG, and is also on Steam which generally outsells GOG anyway). Not sure how many of those people he can reach out to, but there's a market out there buying similar-ish games, I hope.
Nah, it's a fair point. I think I'm probably underestimating just how much desire there is for another game in the mould of the Fallout games. I'm probably just a bit more concerned about how many people associate those Fallout games with Wasteland.
I mean if this was another Icewind Dale game or PS:T, I've got no doubt they'd get the funding and more. Those games hold significant sway on their own though, something I personally don't believe Wasteland does. Hopefully just the type of game it is, is enough to pull it through though and hopefully that proves to publishers/developers there is a market for this type of game.
Again though, is 1 million enough to make a fully fledged isometric RPG in today's market? People are going to be expecting this to be up to the standards of Fallout 1 and 2, but even those games had significantly larger budgets and they were made over a decade ago.
