Welp.
There's this one pc game called Silver, made by the now dead Infogrames, that I just love to bits. Apparently it wasn't super succesful when it was released for some reason or another (prob because it was kinda buggy) so basically nobody knows about it today, but to me its truly a hidden gem. Its an action RPG thing that, despite having a really generic plot (wizurd has kidnapped ur sexy wife bcuz reasons, hur hur), had this really interesting fighting system in which you had to do certain mouse movements to perform a certain type of attack, for example, pressing the right mouse button, moving the cursor upward and releasing it would cause your character to perform a lunge, etc. While the character models consisted of a bunch of polygons that would make final fantasy 7 character sprites look detailed by comparison, all the environments consisted of animated pre-rendered that just looked beautiful as all hell (at the time).
I'm still searching for a copy of it to this day, but even then I'd have to somehow get it working on windows 8 ;~;
A more recent one is Wakfu, the only tactical MMORPG in the vein of Final Fantasy Tactics I've ever seen (apart from dofus, which is made by the same company). I keep trying to go back to it, specially now they completely revamped the way character statistics work, added a new class and reworked the class of my highest level character. However, I have nobody to play it with. Literally everyone from bay12 that played it left, and this is the kind of game you should enjoy with other people. Its not that people hate it, it just... Doesn't seem very attractive to most people I guess.
There's also Messiah, which was this really weird third person action shooter thing made by monolith (i think) with a possession gimmick. Essentialy, you're a derpy angel sent by God to save a super cyberpunk earth from Satan, and the main way to achieve this is by possessing people along the way and make use of their special abilities. Its a really neat concept I enjoyed a lot and that I wish some other games would've used as well, but I never ever found any game that did it in the same way that Messiah did. Buggy and dated as all hell, but I kinda enjoyed it. It was basically unfinished when it was released, so its no wonder people didn't like it.
