Well considering ijji gives us updates to Lunia instead of nothing for months and months from game&game and 12foottall, I consider them to be a "good host" company. As for the cash shop part I think their money hungry just like every other company out there.
I think Nexon is still my favorite hosting company though. I wish they would take over Lunia
I use to play Maple and they did a good job with it imo, and now I've come back playing Vindictus with them and they do a very good job at updating it constantly, having events (in game and forums), and giving out free stuff every once in a while. (Looking forward to Dragon Nest too
