SS2 is my favorite game of all-time. Yes *gasp* Tron 2.0 is not my number one game. It's not even number two. That's reserved for Deus Ex 1. It has to settle for number three.



If you've never played SS2 before, now is the time. Though, be aware, that there are many additional fan-made patches that can be applied to the GOG release to make it that much better. As-is, you're not getting the best experience. There are also additional expansions/missions. They're all available from the systemshock.org site. But it's getting hammered by tons of users today, so you'll probably have to wait until things settle down before you can download anything.

Something interesting to note. There's a bit of controversy brewing. Apparently, some fan-made patches were used to update the GOG version, to enhance it and make it playable on modern systems. But Night Dive/GOG did not give any credit to the fans. In fact, they were claiming the fixes they made to the game were their own work.
This isn't going to stop me from picking up the GOG release. (Just to support future System Shock content, not because I need it.) But I do hope they come clean about using community made fixes. They have acknowledged using fan-made content in the past, but this time they didn't for some reason.
I know that - if Tron 2.0 shows up on GOG some day, and they use materials from the fan community without acknowledging it again - I would get pretty annoyed.
