Generally I like gameplay elements, but sometimes it actually hurts experience:
- Aselia — doing other routes is truly annoying due to unskippable and very repetitive gameplay. Even if you cheat and raise your chars levels to 99, its still VERY burdensome to walk around that huge map.
- KnS — same thing, unskippable gameplay made it hard to play all routes. My thoughts upon getting True End were "ugh, finally done with it, no more same damn map movement lookups".
- DBBA, Sengoku Rance and pretty much every other AliceSoft game — severe time limit. I hate time limits. Esp. when there's no way you could do all quests/side heroines in said limit.
Also, puzzle mini-games are most stupid thing you could add to VN.
