I'm looking forward to Immortal: Gates of Pyre over StormGate and ZeroSpace. I've been on their discord for a couple years and it sounds way more interesting, at least if you care. In terms of gameplay they're taking lessons from how SC2 Co-Op worked and integrating commanders into the MP and SP from the start. The aesthetics are unique and don't just look like a ripoff of WC3 or SC2, even though IGP started out as an SC2 mod titled "Vanguard" (look it up). The worldbuilding is very different from the extremely generic designs seen in SG and ZS, and it has much more depth to it too: the team actually bothered to give the sides actual cultures, ideologies, motives, etc and not just write them as mindless zombies that obey whatever deranged whims occur to shallow inconsistent main characters. From what I've heard of their campaign plans, which they intend to release as DLC after releasing the SP/MP/CO modes for free, they intended to write their campaigns as a multiverse of timelines in order to give every side a chance to shine rather than a single canon that will inevitably favor one side over all others.
By contrast, I don't find SG and ZS remotely interesting. I'm one of those weirdos in the 80% of RTS players who only plays SP, so I'm concerned about meaningless things like "is the writing any good or just more stupid?" SG and ZS haven't given me any confidence that their story modes will be remotely interesting or well constructed. ZS is advertising romance... like, what? Why? RTS doesn't need romance! If I wanted to play Mass Effect, then I'd played Mass Effect, not a ripoff of Mass Effect with RTS game gameplay crudely bolted on. SG hasn't revealed much about their story, but what little has been revealed doesn't interest me and makes it sound like humanity and the demons will team up at the climax against Amon again... which I have zero interest in.
Going back to IGP, two of the revealed races serve Great Old Ones (the lorebook literally calls them that) who intend to reformat reality into something they find more conducive. Everyone else will die as an unintentional side-effect because they're weaklings. I love playing races like that and I'm glad IGP is bringing that back after the prior decades of RTS games ignored it or worse did a bait-and-switch where the monsters were revealed as misunderstood good guys all along.
