Impressions time!
PSO2 - 750+ hours. I've played it on and off for the first 2 or so years as the leader/sub leader of the NeoGAF team. Has the most fun combat in an online rpg that I've experienced. I still come back to the game after the bigger patches, but with most of my friends not playing anymore, I manage to play solo for a day or two before I clear the new content and get bored. Sadly, I doubt that this will change any time soon.
I tried playing PSO2es for a while, but while fun at first, it wasn't good enough to keep playing.
Phantasy Star Nova - I've played the first and the TGS demo I have mixed feelings about it. They've released the list of balance/system changes based on player comments, but I really hope that they fix the performance. Framerate drops in a game which hugely relies on well timed guards/dodges can be very annoying. Guess we'll see in the second demo.
Phantasy Star Portable 2 Infinity - Cleared it about a month ago to get in the mood for the new PSO2 patch. Fun game, although I'm sure it would've been much more enjoyable if I played it when it was released. It didn't age terrible, but it feels a bit clunky.
Monster Hunter - Back in the day I put a few hours into 3rd and 3G, but didn't find it fun. When 4 was released I spend around ~100 hours on it and fell in love with the series. The online multiplier and vertical movement were the best additions ever. Currently playing and enjoying 4G with 50 hours on the clock.
God Eater - Tried playing Burst on the PSP, but was put off by the camera controls. That said I gave the series a second chance when GE2 was released on the Vita and cleared the whole story while thoroughly enjoying it. Sold the game soon after because I don't really like soloing in these types of games and the multiplayer patch was still far away at the time. I'm pretty excited for GE2:RB and I'm sure I'll put many hours into it.
Lord of A - Aracana on the PSP was terrible. Apocalypse was my first Vita game which I bought together with the console on the release day. I think I put around 40 hours into it, cleared the whole main story and got bored during the post-story extra stuff with stronger versions of enemies etc. Still, a surprisingly fun game.
Final Fantasy Crystal Chronicles - Cleared the first or both (don't remember) DS ones together with 3 friends during summer holiday. Despite a few shortcomings we had a blast. Never played the GC/Wii ones, but seeing some of the impressions I guess it's for the better.
Regarding Final Fantasy Explorers, I've played the demo during the TGS and it's not FFXI/FFXIV lite. It feels like a spiritual successor to Crystal Chronicles with some elements from the online games more than anything else. Still, I'm pretty excited and will get it day 1.
Freedom Wars - Bought it digitally, cleared the story and tackled a few of the high level missions. While the core gameplay isn't bad, some of the story stuff feels really half baked (and sometimes straight annoying). The balance is all over the place, with one gun dominating over everything else. Even with the recently added PvP I doubt that I'll play it again. Not a bad game, but could've been so much better.
Toukiden - Got bored after a few hours and an Xth quest requiring me to kill the same monster. It just didn't click.
Soul Sacrifice - For a long time the original Soul Sacrifice was my favorite "hunting game". I think I even platinumed it soon after the release. When Delta came out I bought it, cleared the new story stuff, did some online with my friends and sold it back. Can't wait for SS2 though!
Ragnarok Odyssey - More action focused hunting game with not so much depth. I enjoyed it for what it was, but it's nothing to write home about.
Sword Art Online: Hollow Fragment - For some reason the battle system just didn't click with me. Dropped it twice and went back to normal MMOs.
