NWN EE is excellent, my attitude toward that game completely changed after revisiting it in this version.
I was young when it was first released, I would have been 16 or 17 at the time and I'd been so excited for it when announced because of my passion for each of the Infinity Engine games. When it was revealed to have been made without the pre-rendered backgrounds and isometric view but rather 3D polygonal models in a similar environment with rotatable camera perspective and would be using the 3rd edition ruleset, I was heartbroken. When it was revealed to be essentially a toolkit with a focus on multiplayer and custom modules I lost almost all interest. It wasn't a game I purchased back then, though I did try it at a friends house and everything except for the character portraits and the UI (though inferior to Baldur's Gate to me) felt grotesque. I later bought a copy of the Diamond Edition in a bargain bin and don't think I'd ever installed it, though my wife played both it and the sequel at some point around 2008 or so.
Encountering a dearth of appealing CRPGs around 2019 and having been familiar with Beamdog through the enhanced editions of the Infinity Engine games, I figured I'd finally retry it and try to look past the ugly presentation and multiplayer elements. And as it turns out, so much time had elapsed that I actually found the graphics endearing. The character portraits are some of the best in any CRPG and although the environments are sort of dull I found all of it pleasing to interact with, unlike the revulsion it elicited from me twenty years ago. Then I tried the custom modules which Beamdog hosted from within the games download client and my opinion went from mild enthusiasm to full-blown love with the remake modules of both Against the Cult of the Reptile God and the first two Eye of the Beholder games. I felt such regret that I was so ignorant back in my youth for having not given the game a proper chance; granted, at release there weren't any serious user modules yet and the base-game campaign is weak by comparison to what would eventually be released, though today I like it for what it is. Playing Against the Cult of the Reptile God however had me feeling almost as if I were playing Temple of Elemental Evil. I have a copy of that adventure at home and seeing the few video games that actually manage to bring source material to visual life, like the first Baldur's Gate using Volo's Guide to the Sword Coast, for instance or the aforementioned Temple of Elemental Evil by Troika really appeals to me in a way no other games do.
Grimoire being on sale for one dollar ought to be without question bought, the depth and quality of what I've experienced myself so far and have read about online in that game is to where such a price is obscene. I'm glad I bought my copies at the full price because games like it come along so very rarely that I would feel awful to have paid such an insignificant sum at firsthand. A game like Grimoire should be supported to the fullest extent possible in my opinion, to show that there are still people interested in them. And the other games mentioned earlier in this thread like Eye of the Beholder series, Lands of Lore (the first game), Wizardry, Might & Magic, Dungeon Master and the rest are all worth playing. Lands of Lore is probably the easiest and most simple of the games in this genre that I've played but make no mistake this doesn't mean it is anything less than a masterpiece.
