>>34622033Story heavy fangames are annoying, for two reasons. One, because pokemon in its essence tends to suffer when it gets too story heavy (whether or not you liked SM's story, you have to admit upon replay there are way too many cutscenes; it's why I've only ever finished one main campaign in gen 7, and I LIKED Lilie). Two, 99% of people are shit writers that think edgy adult humor or themes is warranted (it's just annoyingly jarring in pokemon games since fan writers are usually super fucking hamfisted instead of subtle like the main games).
Adding new types or fakemon, because new types are extraneous and fakemon just generally look shit.
Using the gen 5/7 EXP system, in general, especially in gens that aren't gen 5 or gen 7. It isn't balanced properly in its own gens, so Pokemon Naturia trying to use it in gen 2 failed miserably.
There are probably more, but those are some major offenses.
