My gaming hasn't exactly been great for the past couple of years.
I ran a Savage Worlds game based on Legend of Korra as the gamemaster. I consider it to be my most successfully ran game.
After that, it was all downhill. I ran a game of Rippers in Savage Worlds. It was going good, but now that my group was more comfortable in tabletop gaming, they began powergaming and stopped roleplaying as much for the most part (although one of my players is an awesome mix of roleplaying and optimization). It fell apart right before they faced against the BBEG. Ran a short superheroes game, which imploded after like four sessions because of a few new members to our group. They weren't really a good fit and caused more trouble than good stuff they added.
Finally switched out from Savage Worlds with this group. We played a little bit of D&D Next, but the game fell apart again, although it was because of player stupidity. Attacking each other, they've lost all of their teamwork, and constantly ignored plot hooks. We went two sessions with absolutely no plot development-- just bar fights, picking fights with city guard, and then one of the players attempted to sell his party members into slavery in the Underdark. I canceled the game after that.
Since then, I haven't gamed for about two months. I got some people (a whole new group) who want to play 13th Age, but that pretty much extends to "I want to play 13th Age" but when the agreed session time comes around, no one has a character sheet and we end up playing board games instead. After this happening three weeks in a row, I gave up on it.
I really want to play 13th Age. Hopefully as a player instead of a gamemaster for once.
