I recently completed a full 100% playthrough of PoE + Expansions for the first time. What a GREAT spiritual successor to the Infinity Engine games...
What a coincidence, so did I. But my impressions are completely different.
First of all, PoE is full of ideas that seem good, even excellent in theory, but fall flat in an actual game.
I mean, plot about gods being fake? Awesome! Animancy, watchers, ciphers, the entire soul-magic-thingy? Cool ideas! Kinda early modern setting, with colonialism and widespread use of fireams? Nice!
But then, the gods thing drops on player out of nowhere, without any proper foreshadowing. Like, should we care the gods are fake? Does it change anything? I mean, outside of the Eothas stuff, it didn't play any role in the story before Twin Elms, so... uh... okay?
Animancy is decently developed in second chapter, but right when it seems that the devs cooked something cool out of this diea, it gets thrown out of the window. We are introudced to cipher-spies, but never actually see this theme exploited. For fucks sake, mind reading-controlling-fucking agents, that's such an nice idea, and you do nothing with it?! Not even in a sequel?
And the combat system/mechanics are so... bland. And shallow. What's the point of all those useless spells, like grimoire imprints? Padding out later levels? Too much is dependent on the charlevel, it's silly that one level is an equivalent of most powerful item bonuses. And while I am not completely opposed to Sawyeran "might is the most important attribute to mages!", it makes all builds samey and stale.
There are some good parts - White March pt. 1 a is god-tier expansion, with excellent writing, superb encounters and good sense of scale, which unfortunately gets thrown out of the window (gods again...) in part 2. Shame it screws up the overall game balance, even with level scaling.
But honestly, I think the greatest thing that came out of PoE, the only thing that will have lasting impact on RPGs of the future will be... quality of life mechanics. Fast mode, stash mechanics (when it fits), carefully crafted desrptions and hints... Now that I play P:K without those, I learned to appreciate them even more. Still, not enough to make PoE a classic it wants to be. It's a good game, but only that. Wasted potential.
