Playing Pool Of Radiance got me learning the ins and outs of 2nd edition AD&D and I came to the realization today that I prefer games with a magic points or mana system. Probably because I grew up with JRPGs which exclusively deal with MP over spell slots. Don't get me wrong, D&D is great, but it's such a pain when you get into battle and you realize you forgot to memorize Detect Magic and now you have a bunch of potential good loot.
I'm pretty easy going about spell slots in ttrpgs because of the social and improv aspects of the game, not having the right spell for a situation or being out of certains slots can be fun for story telling and for team work. Knowing that I can work stuff out in creative ways with other players and the gm softens the annoyance of it.
In crpgs however, I kinda hate them because there's so much more combat. I end up just hoarding spells and not doing anything interesting or I blast them willy nilly because resting is readily available at the press of a button and neither option is good in my book.
