Over-automation of gameplayLimiting what you can do by doing it for you. This mostly applies where the automation takes away things you could otherwise have done. In RTS's, prebuilt bases and squads would count (Damnit, if I want to spell out my name with houses, or make an army of villagers, I should be able to).
"RPG ELEMENTS"
This bugs the crap out of me in games. Most games with "RPG elements" tend to use heavily stripped down stereotypical-RPG elements, and my main complaint with RPG's is the already oversimple, generic mechanics many use to begin with.
Minor graphical errors
I would expand it with:
Shoddy graphical work(Note, this applies to "professional" AAA games, where for the cost and development effort you would expect better. It does not apply to amature/indie games, where the resources and skills simply may not exist).
Holes/gaps in models, ugly seams in textures, low-resolution bump maps. Eye-bleedingly bad animations, skin poking awkwardly through armor/cloths etc. Im looking at you, TES III & IV.
The Sacred Quartet of Elements
Completely agree. The things that represent magic are not even particularly magical. Why is water even related to magic? It just seems that fire/water/wind etc magical elements are there because every other game uses them. It brings me back to my "Why are RPG's so damn traditional" peeve. Lots of RPG's tend to do certain things (both mechanically and conceptually) because "Thats the way its done, damnit".
