Planetside is a decent enough game. It is pretty stable and has some cool features that you don't find on similar titles like Battlefield 1942 or Quake/Unreal. The question is, does Planetside offer enough over these other titles to pay for the monthly subscription fee?
To me, it did not. I really like MMO persistant games, but Planetside just didn't seem deep enough to gather my attention like EQ or DAoC. And I had a hard time justifying the monthly bill when I could play BF1942 with it's excellent player made mods for free. I don't want to sound like I don't like Planetside, it's a good game, but imo it needs to offer more then it does for a monthly subscription fee.
