Back then I played Warcraft 3 ladder games and I hit my skill ceiling quite fast because my micro was simply too bad/slow. I still very much enjoy real time strategy games. Is there any real time strategy game that is played competitively with an active community where micro is not that essential? (Ruling out Star Craft 2.) Besides real time strategy games, what other games are out there being played competitive with an active community and where clicks-per-second are not too important?
If you liked Slay The Spire despite it not being competitive, check out other deck building roguelikes like Monster Train and Peglin. You could also play TCGs using unofficial free simulators like Yugioh Omega, but those will likely have a steeper entry curve because only veteran yugioh players are on there vs Master Duel having millions of scrubs and bads to ladder against.
