Try this until then: http://pilole.com/uukrul/

It sure has different graphics but it seems to be quite decent, I haven't had the time to try it yet though.

I'd be temped to have Neuromancer again for the first time since C64 5.25 inch floppy (the Amiga version looks better then PC though, saying that)
And maybe a shout out to Bloodnet too, while I'm in a Cyber mood

That's all that I can think off top of my head

Currently the only game that comes to mind that would be an instabuy is TIE Fighter. My backlog is simply too large at the moment to by adding to it on a whim. Well, I suppose you could also add Torchlight 2 to my instabuy list if by some miracle it shows up here on Thursday; I'd be willing to shell out up to $40 for that if it got the GOG treatment on release day.

To The Moon was an instabuy. I didn't care back then when it first available here since it look like old JRGP.

But yesterday I play the video and it was nice, and since 60% off, I buy it right away (and some of the music is done by Plant and Zombies musician).

I'm instabuying all games I plan to buy (I have a list). Also, I instabuy games that I see a risk they might be pulled off soon after the release (Sid Meier's Pirates and Colonization - although they were on my list, but I'd instabuy them even if they weren't).

Albion... Oh how I love this game. One of my fondest memories of gaming is starting this game , playing for a couple of minutes on the starship and than BANG - three-titted alien in the cutscene! Good times, good times.
