This has been the only game I've preordered in years, since I wanted the box and extras with the LE, but I only got around to finally clearing Ciel's routes yesterday, after having blasted through Arcueid's route like a man possessed upon receiving it. Now I'm just cleaning up the remaining bad endings to see all the "Teach Me, Miss Ciel" clips and picking different options to complete the flow chart and make sure I've seen everything I can. I'd like to get the backstory for Gouto Saiki and figure out who the girl in the jacket is that pops up here and there throughout the game.
I'm looking to probably play the original again, now, so I get the full story without having to wait for the remake of the Far Side routes to come out in who knows how long. I did play through Arcueid's routes and started Ciel's way back in the day, but wound up getting distracted and moving on to other games without ever finishing up the rest.
I have to say, I mostly enjoyed this remake, though the lack of a true ending for Arc was a little disappointing.

Ciel's endings were so depressing for me. The first was just sad, because she dies without ever being able to enjoy her time with Shiki. The true ending was pretty solid, I just hated having to fight Arcueid and being so mean to her to get it. That said, I wish I could a bit more follow up for what Shiki and Ciel get up to after she takes him out of the schoolyard to her apartment. In particular, I want to see the fallout with Akiha when he shows up after over a week without contacting her, with a girlfriend in tow, heavily injured and turned into a half vampire.
Overall, I'm looking forward to the Far Side remake, but I need some more Tsukihime in my life in the meantime.
