Looking for an Opensource engine (ready-made script) for online games?

Question

CMS

Kind.
In LAN, the people demanded to install a thread of an online game in order to play en masse. At first I thought about putting something like BC or ganjawars, but I decided not to let myself down under the article.
Are there ready-made, working online game engines similar to the same BK, ganjawars or something like that.
Acceptable languages: php, python, but you can consider other
databases: MySQL, PostgreSQL
The extreme option is a client-server game ...
Maybe someone had to install, finish off opensource online game engines, recommend.
As always, pluses to everyone who checks in despite the comments, the main thing is not to downvote;)
Thanks for the answers and I hope for understanding :)

Answer 1

The whole point of the issue is not in the engine, but in the graphics.
You can also use a null engine - no one will show you anything. But for the schedule they can present.
Creating graphics in a game (large game) is the most time-consuming process, therefore, as such, there are no browser-based OpenSource games in Russia. There are no fans to draw for free.
Although I remember, in ancient times, there were browser-based OpenSource games in Russia, but the graphics in them were at the level of school drawings. Now they are dead.
I advise you to watch such games in the West or look for "browser dinosaurs".

Look at www.glorylands.gr/ I was interested in her about 1.5 years ago - it seemed to look good. At the moment, I don’t even know if they abandoned development or are working on a project
