@xianc78 the majority of the plugins i'm using are all by the same 3 people that even recommend each others plugins on occasion so i'm good there for the most part. i did have issues in the past with one plugin that i really want to use that can't be used with some other ones i absolutely need. the plugins that i have also tend to affect different aspects of the game, and the ones that affect the same aspects are made by the same creator and meant to work together or they're made/heavily edited by me to meet my needs and not cause other issues.
this is the only issue i've run into where the plugin disagrees with the engine itself when having too many sprites on screen lol. 99% of bugs are of my own doing, but this one wasn't and i would consider it an outlier.
i also have made sure that the plugins i use are a-okay for commercial games. i've never seen in any terms anywhere that say you can't use someone's plugin with another one, either. i think, in general, the RPG Maker community is pretty good about letting people do whatever they want with their plugins as long as they aren't just redistributing them. the commercial licenses you sometimes have to pay for, but that's about it. and i do have all of my ducks in a row there. sadly, the plugin i needed to remove i had to pay for, but it was only like $3 and i use a couple other plugins by him so it's whatever.
@xianc78 i agree with you though, it's best to use as little as possible. i'm not trying to have as many plugins as i do mods for skyrim you know xD
