This sounds like my situation
I've only played through Phantom of the Inferno, one ending; Tea Society of a Witch 1 ending, and Ever17 2-3 endings [not going to stop till I get the final ending!]; While Yo-Jin-Bo, the Exodus Guilty games, Hourglass of Summer still to go~
The only time I've been able to play recently is usually in the dead of night/morning, which leaves me sleep deprived
Whenever I play through visual novels, I make a point of starting them only when I'd have enough time to play it through to the end. I do not like starting something, going to work during the week, then picking up where I left off 5-6 days later. Especially when Phantom of Inferno takes a week full-time to finish and I do not have time to replay large chunks to refresh my memory. As a result, Hourglass of Summer has been on my back-burner for 2 years. Sad, but true.
Since you seem to like Hirameki stuff, I'll give you my comments for future reference:
Phantom of Inferno (Completed with all 10 endings)
-Definitely worth it. I first played this 2 years ago, and I made a point of replaying it during the summer since two friends were interested in checking it out. I only caught 7 of the 10 endings when I first played it (before I made a point of catching every ending -- this was my first, after all), and I had come across the PS2 version's official player's guide, so I decided to give it another whirl. Definitely better than the first time around since I got to see everything.
Day of Love (Completed with every ending)
-Charming, but not really recommendable. Extensively censored, to the point that only two of the endings actually feel complete. Don't pick it up unless you have cash to burn.
Amusement Park (Finished with only 2 endings)
-I can't give a fair judgement this early, but so far, it seems alot like Day of Love, but with a better scenario. I've noticed some censorship, but nothing seems too bad compared to DoL.
Ishika & Honori (Stopped playing after an hour)
-BORING. Annoying characters, dumb premise, and the story changes are influenced somewhat arbitrarily by whether you attacked, used magic, or defended in its equivalent of a random RPG battle. Not recommended.
Ever 17 (Completed with all 8 endings and all 3 epilogues)
-THIS is the reason why I make a point of playing through every ending within the same expanse of time. The hype you have heard about the Final Chapter's ending is well-deserved. If you enjoy endings like The Sixth Sense or The Usual Suspects, you will love the final scenario. It's not my favorite scenario in the game (that would be reserved for Tsugumi's ending), but it's definitely unique in the best sense of the word.
I own every Hirameki title except Exodus Guilty Vol. 3 and Dragonia. Hourglass of Summer and Exodus Guilty are at the top of my to-do list, once I finish with Dawn of Sorrow and beta testing. Sucks that I return to university next Wednesday...

Fortunately, I only have class 3 days a week. University life can be sweet.
On top of that, I have Portrait of Ruin, every Zelda title released since Majora's Mask, Tsukihime, and the releases from Insani's Altogether translation festival left to go through... wait a sec... I already went over this. Sorry. I have a tendency to rant when I get into something.
As for fan translations, I have kinda phased them out unless the game looks
really good. When free time is scarce, you have to be discriminating. That's why I've stopped playing RPGs that take themselves
way too seriously (a serious tone can be nice, but when the story becomes cliche, it's time to move on). Action-RPGs and Side-Scrollers are more my cup of tea. I have never had the patience for Strategy games, despite the fact that I would really like to play through my copy of Growlanser Generations.
Nice mugs & shirt, Joe. Kinda reminds me of the T-Shirt my brother got me. It reads: "1f j00 c4n r34d 7h15, j00 n33d 70 g37 l41d."
