Ple-Sen
I bought Reforced back in the day, though I never actually launched it even once.
First came the vanilla, then the Soul Harvest addon, then the Fallen God addon.
Then Reforced came out. It's a rework of vanilla that brought the mechanics, balance, and graphics up to the level of the latest addon. But the story campaign there remained from vanilla. And the addons kept their own story campaigns. That's why, of course, the addons are still sold separately.
Some aspects of the story/quests were slightly changed. For some reason, they cut off the possibility of a better resolution for a certain story quest, as if the game was overflowing with optimism before that.
In general, I've been thinking about writing a review of the third Spellforce + Slow Harvest at some point. Maybe I really will get around to it later. There are good moments there. Weak ones too. But overall, it's very obvious that the writer was the same guy who wrote Endaral. Because it's exactly Endaral in spirit, and there are so many retcons/reinterpretations that you can't bring yourself to call it part of the old world, despite a number of shared names.
