It's non-competitive (I'm burnt out with SC2 ladder a bit), but I've been enjoying Cataclismo, Settlers 3 (THAT is a throwback), and I'm eyeing They are Billions.

Some SC2 youtubers are now covering Mechabellum, Tempest Rising, BAR, AoE4, and some in-dev titles: Battle Aces, Immortal: Gates of Pyre, Zerospace, and of course Stormgate.

These are all on my list but I'm busy enough playing Warframe ^^'
