Again, separate from the 52 game Challenge, let's give this a shot
Top 5 games played in 2015:
1. Final Fantasy III (DS)
2. Skullgirls (PC)
3. Splatoon (Wii U)
4. Psychonauts (Xbox)
5. EarthBound Beginnings (Wii U)
Worst 5 games played in 2015:
1. Alien vs. Predator: The Last of His Clan (GB) - Slow and floaty, just how I like my platformers...
2. Chaos Legion (PS2) - I can't think of anything snarky to say about this, it just wasn't very engaging at all.
3. Mario Party 7 (GCN) - Urghh, where's the Nintendo 64?
4. Rodea: The Sky Soldier (Wii U) - Wow! this game got off to a rough start, haven't played much but it really isn't all that interesting of a game
5. Billy Hatcher and the Giant Egg (GCN)- I didn't really hate this game, I just kind of wish I bought Super Monkey Ball instead
Systems I played the most games on:
Wii U with 10 games, that include 3 Virtual Console titles, if you don't count that, then it's PlayStation with 8 titles
Game spent the most time on:
I'm gonna hazard a guess and say it's probably Super Smash Bros. Wii U
