Super pessimistic viewpoint, what guarantees the new game will feel like a shitty binklawz mod lmao.
Also if there's no reward, then why did you ever play? What made you do it? Some people like the feeling of progress and it doesn't always have to be artificial. You say things like why settle for something that doesn't feel like toribash, but have you even played tb next? If you have then damn my b you got me, but it's still your opinion.
You just kinda seem like someone who doesn't want change, even if you aren't that's how you seem, I can get it though, people have put time into this and many don't want to start anew.
The problem of the learning curve has always been there, and if people got through it in the earlier days, people will get through it now, hopefully it's fun enough to dick around that people don't get discouraged at not being immediately good.
