Every hobo sequel has ratings over 8 and over 1mil plays, so there should be sequels as long as it gains good rates
That depends the creator can stop making games whenever he/she wants. The only way to tell is if he/she mentions it somewhere or if it actually comes out.
I personally don't like playing Hobo games for too much time. It is funny in the beginning but it gets gross and too violent after some levels. The game's rating is not that high though, I remember it was like 7/10 the last time I played one of the games and I see few differences between the games.
Yes the game isn't tolerant and it is disgusting and violent. But it is fun as long as you DO NOT do what he does. I think there won't be the fifth part (the idea is the problem).
I'd just like to state that I haven't played any of them...ever. I responded purely off the idea of how games get made into series.(That's more what this thread is about, no?)
I don't know if it's good or bad, but It's all up to the creator.
Part 1 was a classic, something like Buggerman from sega i think, burping, poo, pee, spit, it was discusting but fun, and then they introduced guns, rockets, and perhaps ruined that something that Hobo had. But i would still play new hobo till the end
