Just a hunch but once they got some considerably progress they would have something like
'Oh shoot, guy look at how marvelous our asset work in 4D engine, gonna redo them all over again, please support me thx bye!'

' Oh shoot, we have a brand new project that we excite to working on, it'll be a turn-based game like moving piece of chess against enemy team, in the mean time will put the action game on hiatus to have this new project fund them instead!'
::X years later::
'Oh shoot, we're now have card game project that we're so exciting to work on, will put a chess game on hiatus for now and----'
Dunno tho .... give them a couple years and see if my hunch will be right
