I stopped playing regularly since last September, but only because the game was starting to hurt me financially! When I finally reached the Third Tier, the difficulty spikes were so massive that I started using so many of those Energy Packs and buying a few small ones every once in a while.
When I realized that I had spent over roughly the same amount to buy 3 full price games, I felt hurt bad.
When Phantasy Star Online 2 was announced as F2P in the West, I dropped this like a bad habit, hoping to save a little cash.
I have been marginally interested in the new stuff that's been announced, but very rarely I've gone back and played it. Though I have to admit, even though I haven't played it much, I did peek in there and I've noticed that it's quite a different game than before.
More enemies, a much better UI, better match making, graphical overhaul, at least, it's nice to see that the money I spent on this didn't go to waste.
