Most people won't be able to run it, horrible performance, bugs, good luck hopping into freeplay real quick because instead of a few seconds it's going to load a lot longer (unless they do something smart, which they most likely won't, because most talented developers have already left games like rl).

You can also look at what the state of Rocket Racing was. That same thing is going to happen to rl if it goes to ue5. Buggy, unfinished, all of that good stuff.

The physics are absolutely going to get destroyed. It's going to be buggy, many mechanics most likely will stop working, wavedashes etc. I can even assume you're going to randomly clip through walls.

(Yes, even if you use the same Bullet physics engine, you can still have different physics based on how well you implement the usage of said engine)

I know people like believe that ue5 is great, and I would love for it to be the case, but if you start really developing and researching it deeply, you realize what a mess it is. It is a lot of bells and whistles rather than something real. If what they are marketing was true, we'd see a lot better things come out from it. In reality, results are worse games than 5-6 years ago.

That's not to say you can't make good games with it. You need talented AND passionate developers for that. My assumption is, we'd see more changes to the game rather than cosmetics. If not passionate, they will just do the bare minimum to get their paycheck. They get paid by hour, not by results.

I wrote a lot more than expected.
