I don't think Tactics is a prequel. As I said before, my memory is fuzzy, and I guess it does make sense that the beginning of Tactics story takes place before FO2, but they are so loosely related, its hard to really consider it a prequel, or even a sequel. Its just a game that happens to take place in the same world I guess(and has probably been ignored in the greater continuity of the series).

Yeah, this is pretty much how I remember it too, though it's been a really long time since I played it.
 
Even if it is a prequel the Fallout games are so standalone that it doesn't really matter anyway, the connections between the games are really more relegated to the backstory rather than work as some active sequence of events. Like one of the biggest examples I can think of as far as connections between the games go is that the NCR are the BIG DICK in California by the time you get to New Vegas, and they really only exist because you went around helping a bunch of otherwise hopeless farmers back in the first Fallout game. That's not the sort of thing that really matters when you're playing New Vegas, you're not missing out on anything critical by not knowing this, it just gives slightly more interesting context if you've been paying attention to the way all the sects of people function throughout the series.

Speed running GTA3 is hard.

There's a guy I work with who spends a lot of time gathering data so he plays T.D. games on kongregate. 

These are a few games I've played mostly because of GOG sales.
 
Gemini Rue: I liked this one a lot. The plot twist was pretty well constructed. The puzzles were pretty easy but there were some really greatly designed ones. It gets an A.
 
The Witcher: I got it free from a GOG promo. Basically I can't get myself to like this game. It kind of seems like they put the worst elements of Fable and Neverwinter Nights together to make a rather bland experience. Also, I'm cool with the idea of being able to have sex in an open world game, but the way they present it (ridiculous cutscenes with hardcore porno sounds and then receiving a trading card for each lady) was pretty gross and made me feel kind of put off. I also just really don't care about Geralt at all.
 
The Cat Lady: This is a pretty fucking great game. Sure, it has its plot holes and at times it plays more like an interactive cutscene than a game, but the art direction is great, I genuinely liked the main characters, and the themes are pretty heavy and thought provoking. I recommend it.
 
Wasteland: I haven't gotten too far in this yet, but I'm still on the fence as to whether or not I want to keep playing it. I'm a huge Fallout freak and I play through at least one of them annually, but while I can see this game's influence it really hasn't aged well. The mechanics are pretty ahead of its time, but the execution is kind of shitty. Also, the scenario design is just kind of weird (Find hidden cave, kill rabid dog, get attacked by savage children which causes the river to dry up and The Red Ryder to come and attack you for some reason.) I'll mess around with it a little more, but I probably won't play through it all the way.

The Witcher: I got it free from a GOG promo. Basically I can't get myself to like this game. It kind of seems like they put the worst elements of Fable and Neverwinter Nights together to make a rather bland experience. Also, I'm cool with the idea of being able to have sex in an open world game, but the way they present it (ridiculous cutscenes with hardcore porno sounds and then receiving a trading card for each lady) was pretty gross and made me feel kind of put off. I also just really don't care about Geralt at all.

 
Ahaha I can see how say, a 14 yea old who can make games would make this kind of things but to think that a studio of people made this is hilarious. Can you imagine the design by committee meetings? I'm not against the idea of being able to copulate in games (sex is less offensive than gore, realistically?) but the mentality is comical. It's almost exactly James Bond. This is what you must aspire to be, a banger of many women and a slayer of the others. Austin Powers has been dragged through space-time to the 16th century England to find women to fall on his sword: you must save him from the onset of syphilis, and ultimately, himself.
