Like I said before, most erotic Unity games are low effort messes made by dumbies.Obviously in these situations where you port a game it's always good to have somebody that's comfortable working in the engine. But I get the uneasiness from people regarding the engine, as it's a low-entry, relatively easy to learn engine which in turn ends up with a lot of poorly optimized games.
Last I checked you get advanced diagnostics/debugging tools if you have a subscription to Unity, for most people just making a simple game they are less likely to go for any of the paid options which makes it more likely to have a buggy/poor optimized game which people run into.
Unity is easier to learn than Unreal Engine, but of course if you are amidst of making a game and doing a port it's best to have somebody that knows their way around the engine.
Any team with high level coders is going to find their way around any engine and then it just comes down to personal preference and possibly budget.
But as I said Genshin Impact positively surprised me, I was about to tell somebody "Unity Engine is shit, just look at these buggy poorly optimized games" like 6 months ago and then when I opened up the Unity Games list and spotted Genshin Impact on there I was flabbergasted and didn't post my reply haha.
I won’t ask you to believe I’m not a dumbie, but I hope you can see this project is anything but low effort.
