Oh, I played enough (Brood War especially) that I still know 80% of them.
I highly recommend you try the SC2 Zerg campaign. Terrans are boring, so even if you liked the game that made the original SC2 less fun for some. In the Zerg and Protoss campaigns they added this cool unit customization thing, for example for zerglings you pick
1 of 3 mutations: +10hp or +50% attack rate or +60% movement speed
1 of 2 strains: Jump up/down cliffs or spawn 3 instead of 2 and a lot faster
You get that for all the units and it really changes things up. For some of the units like on Protoss one of the strains will replace the Stalkers with Dragoons instead.
I also saw that Inscryption is on GP, I definitely want to give that a try.
