No, not a great time to mortgage the house and go all in.
If you have a passion for making games (and presumably a skill set) then start as a hobby, make a game or two and learn the ropes.
Unless of course you have a very large bag of money. In that case figure out what would be really cool and then hire a great team to make it happen while you sit back and OK each build before releasing more cash. Ultimately I think scenario B is probably a lot more fun.
