Yes, J.B.Harold series were quite old Japanese PC games. but I didn't know English version was existed.
I didn't know Project Hacker, but it seems an interesting adventure game.

This thread made me want to re-play 9-9-9 game, so I'm now playing it.
The game has awesome atmosphere and puzzles. :)

Agreed, can't wait till the weekend to play it more. I picked door 7, because I wanted to see Seven and Clovers story's the most. Seven seems to be hiding something, Clover is looking for Snake, and there's something strange about him.

There's something weird about Lotus as well. I was trying to stay with June, but the numbers didn't work.

Phoenix Wright is also brilliant, not guilty verdict on my first case yesterday.

Oh, that's the easy part. It only gets harder from here.

To be fair the game is constructed where you generally have to work out and give the correct solution to each part or you simply have to start over from your last save if you run out of chances. When the game lets you fail, it's usually for a non-canon bad ending.

This may be a weird suggestion for games, and it depends entirely on if you like card-based battlers, but the Yu-Gi-Oh DS (and GBA) games can be pretty fun, and huge time-sinks. The 2009, 2010, and 2011 World Championship games even have an OC insert storyline based on the 5Ds TV series and something like thousands of cards in each.

Finished one of the endings in 999, I got killed, was fun though. Going for more endings.
