I’d recommend not giving up on the SC2 campaign and watching some RTS content creators who’ve made excellent educational video series. That said, you identify a common problem for the genre compared to others when it comes to welcoming new players. RTS can be really challenging. Tower defense games may be an easier starting point for becoming comfortable with RTS.
We’re aiming to make Stormgate more approachable to new players than the previous Blizzard RTS games members of our team worked on, without lowering the skill ceiling.
When our game is out, maybe try starting off with campaign, customs, and co-op vs AI—those modes are a much better starting point for learning than trying to dive directly into competitive play.
