Unfortunately, it failed to attract Star 1 users (I suspect that the big factor was that Star 1 was held on for too long and the gap between Star 2 widened too much) and it became a very different game, so considering the age range of Star 1 users, it was difficult to learn something new. I think there were a few users who passed on it because it was over.
However, the RTS genre itself was in a recession for new users to get started.
Anyway, if you look at the works released by Blizzard since then, you will wonder how this company ended up like that.
