Posting an update here for the shows that have been finished for those that may not have seen it yet. These are all the games that have stopped (for now) since January.
Multiplayer
River City Ransom Underground Sadly this one ended as a bust. The game play pissed off the entire group so much, that we rage quit on the final episode. Lots of potential all of it wasted.
Human Fall Flat It is likely we will continue this game again, as they do tend to release official maps a couple times a year. So expect it to come back in one burst in another year or two.

Team Fortress 2: Mann Vs Machine A very fun though short series. It's a shame they never added more to this mode. But if you want to see a group of 6 of us battling it out with robot doubles, then this is your jam.

Castle Crashers I have never finished a game by these creators until now. This was quite a bit of fun despite a rough start. Maybe we shall look into playing more of these some time.

Singleplayer

Half-Life 2 It's all done, a very fun game, though I would remind viewers it does end on a still unfinished cliff hanger.

Final Fantasy III Just recently finished, Final Fantasy III is at times a very tough game, but it was fun to finish, and was a great romp in an updated classic (despite issues with one of the patches).
