AOV and especially ML (and it’s not shocking giving how much bigger player base ML have and how much more money that game makes. It’s quite a normal thing to invest more and develop more a successful product) really improved in the last 1.5 years and they both continue to do so with rapid speed.
P.S. Unity is a good engine overall (on PC too), got a good scaling on different platforms and is a good choice for mobile, btw. Quite a few AAA titles on mobile use it.
Edit: As for VG, I suspect that their code is a mess - optimizations will 99% not happen. It’s not that easy to optimize, can lead to a lot of bugs (and we all know how they deal with them currently) and it’s generally time consuming. I was hoping that they will atleast fix the desync, but currently I doubt that this will happen too… especially with the “bug fixes” they listed to make it look like a big list, but in reality not a single important ingame bug was addressed.
