Bad trends:
DLC for things which would have likely been part of the original package otherwise. This includes micro-transactions (paying to unlock content that is already on the disc).
Genre narrowing. A lot of great genres are dying or dead. Space sims, shooters (think Gradius and R-Type, not FPS), hack'n'slash/beat'em up and more are a dying breed.
Online multiplayer replacing local multiplayer.
Advertising budgets for games being slashed.
Game patching post release and contentless updates.
