.//Something that you could just pick up at your local bookstore (such as Borders):
Hourglass of Summer or Phantom Brave.
They cost around $30 if I remember correctly.
They're non-hentai Visual Novels 3nodding
Phantom of Inferno... >.> Phantom Brave is the NIS tactical RPG that the Makai Kingdom system was spawned off of.
Anyway, yeah for comedy and romance basically if you just want to pick them up at a local store you'd want Tea Society of a Witch... for comedy anyway... Phantom of Inferno basically isn't comical at all, but it's fairly romantic and I actually loved the action in it, there's also a special set where you can get the animation with the game now. Aside from that Hourglass of Summer is a pretty damn romantic one, and it's fairly dramatic with a good amount of suspense.
Anyway othewise if you're willing to order it, Ever 17 is really great. It's romantic, suspenseful, and has a pretty interesting plot. YOu don't get the entire plot until you've played through all four normal "good" ending and then amke the right choices so you can go through a fifth storyline. It's quite interesting.
All of the ones stated so far are non-ero.
As far as ones with ero go you'll have to order all of them. Personally I like the ones from CROWD like X-Change, but those are pretty heavy on the h-scenes. Although they're amusing and have a good selection of characters.
