It's nostalgy i tell you, have a look at this weird forum thread, 70 pages of people being butthurt about age of wonder 3 and it's terrible gameplay too .

It's the cycle of (neckbeard) life.
I remember people being baffled at what stinking pieces of shit Neverwinter Nights 1 and 2 were, and now that enough years are gone a lot of people remember them fondly because they became part of their childhood memories. Even here in on the Codex.
Same with the recent thread about the Dark Alliance games.
I also remember when I played the Age of Wonders in the past and the ongoing sentiment was "Well, at least they are trying to add more things, but Jesus Christ, how comes no one can actually do better than Master of Magic in this genre?"
Eador was also generally dismissed as a half-botched attempt, but now it's apparently a beloved classic.
Spellforce: COnquest of Eo was criticized for feeling a half game (and it was indeed sold at half the price and with a single map because they ran out of money).
And so on.
It's true that this new game has some massive blind spots. Above all, races/cultures hardly having a distinct feeling past the couple of starting perks (which can eventually be obtained by other means like mutations in some cases, anyway). The mutation system is another one.
But you know people are starting to stomp their feet and throw a tantrum "just because"when the complaint becomes "the UI is complete shit", which is not just false in general (there's room for improvement on a couple of QOL details but overall I'd say it's actually GENUINELY good), it's also especially hilarious when you can stop living in your rose-tinted memories, launch right now your copy of Shadow Magic on GOG you didn't even click on once in the last few years (because you didn't, be honest, no matter how much you cry about loving it more now) and realize what a fucking mess *that* UI was in terms of readability and practicality to reach functions comfortably.
I'm not even talking about what I remember, because I actually tried this the other day for a direct comparison.
