I've been following this one, but I'm hesitant to back yet. I've backed a few projects and so far 2 disappointed heavily. Both just did not live up to the promises. So far the only one trending well for me is Bloodstained.
That said, if the gameplay is solid and I believe in the ability to execute on the roadmap they present, I may do 20-40 (depending on the tiers etc). I think I saw somewhere it won't be F2P though, which is a hard thing for me these days with the third kiddo due in a month. For the amount of time I can spend online on my computer, a monthly fee doesn't really add up. Now if it came out on my new Switch that would be something lol (obviously I don't expect this). If anything I prefer models like Guild Wars 2, which I've spend probably $200 on, even without a monthly fee.
