There's been quite a few games in recent years where I notice some system and think "ugh, do I really need to bother with this, too?". Especially crafting or skill point systems which feel slapped on. Some games make them a fun and integral part of the gameplay, some seem to include them because it's trendy and it just adds friction and mental load with little payoff.

I don't mind complexity, some of my favorite games are ridiculously complex (Dwarf Fortress), but the complexity needs to pay for itself.
