I have been reading a lot of negative stuff about how people wouldn’t wanna commit to building maps in SC2 because the way the lobby system now worked, making it difficult to get people into games testing and getting maps even in the pool for the Arcade.
I am just looking for a hobby I have been wanting to do, which is make custom games. Are these things no longer an issue?
The lobby system has greatly improved. If that is your issue it is no longer the case.
The bigger question is the type of game you want to make, and if SC2 is the best engine for it. There was not a lot of competition for it back in 2011, there is a lot of other options which could yield greater results for more work. I’d do some research and decide based on your programming skill level and your personal goals.
