Finished is a subjective statement as well, what does 'finished' actually look like? When was the last time Eromancer shared the vision statement for this game; say three levels with 2-3 mob enemies and a stage boss? Game over sequences etc.
Ero could 'finish' the game now as a wave attack game with 'big wrench guy' as the final enemy.
Only game plan I ever saw was a 'Night City' style stage map, which hinted at a very, very big game (which was never going to happen). At the minute you have no idea on how complete the game is, unless I'm missing something.......
