Quoted from Aurich:It does seem like it has people coming back for more, I just know that with some of his games, like TSPP, you can really enjoy it, but then not want to restart it after a long game, I'll be curious to see how WOZ holds up in that regard once it's settled in. My playtime wasn't long enough to really judge if it was going to start to feel "grindy" after a while. It seems like there's enough to do that it won't be a real issue.
I always look at it in terms of how long I spend actually playing the game. IM, you can 'beat' in 15 minutes, and you'll probably still want another game after that. After playing for an hour, I'm done. WOZ, one game can take an hour, and I'm done after that. Same amount of time, but I've enjoyed WOZ a lot more.
If you're looking for a quick game, you can try for HOADC mode (the most underrated mini game, IMHO). It's much harder to collect than many of the other goals, so it goes a lot quicker.
