In fact there is no engine perfect :
And there is a response saying Esenthel is not so bad in the end and Unity not so perfect lol.

The best is to try it, and be more carefull if it would be some professionnal project involving lot mof money from the beginning :
This is different from indies game making wihout investment or any money invested.
In that case of lot of money invested , the best is indeed to try to find the most information you need about the ability to make your game and have something stable.

But well some MMO using esenthel seems solid. I should try one, just to see performance and how it runs on my PC.

What i find is lacking is simple games (not asian mmos), sold on PC or mobile ?
I don't see any ? or i have a problem to find them ?
why ? strange ?

At least i know games for PC can be made with 3DGS and are sold lol
