This is certainly an interesting concept. I have only played F2P or straight subscription based MMO's previously, but I would be willing to try out this model and would definitely appreciate some "free" play-time. Particularly if I enjoy the game as much as it seems I will. If I'm playing that much and earning credit to play more... seems like an endless, vicious cycle. I'm okay with that though.
I have not played the Everquest games, but I must say if this works how they claim it will, I am exceptionally excited about this concept. Particularly EQN Landmark. As a student going to learn how to make games, I am possibly more interested in the development aspect than I am the game itself, but the gameplay does look really nice. I like the emergent AI and the break from the accepted template character gameplay build. That should really help to keep the game continually interesting a fresh. My only concern would be how much follow up they will implement. Looking forward to needing to choose between this and ESO. Love to play them both, but I know for a fact I won't have the time.
Personally, I am a fan of subscription games. I don't have as much experience with a wide variety as many gamers out there but I have played a number of different titles, and I always hated the cash shop concept. Whether the game required it or not, I always felt that if I was playing a F2P game, I was missing out on a great deal of content or just plain unable to compete unless I paid the money for this item or that area.
I know I was paying money for essentially the same thing with the subscriptions, but I felt like my money was going to a pool the company would use to bring out more content that was solidly made and thought out, rather than another pretty sword or hat that did nothing for my character except make my avatar look like as much of a geek as I actually am, rather than the bad-ass ninja-assassin that I wish I was.
For me, it was a feeling of how my money was used. Whether it was actually true or not, I just trusted my money was being properly utilized with the subscriptions, whereas I felt any money I would have spent to unlock in-game content was just a way for the game company to make a quick buck. World of Warcraft proved to me again and again that I was right in that assumption. The Old Republic gave me hope they would as well. I had to stop playing before I could find out, but now that it is F2P, I no longer trust that I will enjoy it like I once did. I will still try it, but I am not hearing the glowing reviews I once did, and I don't see why the company would spend more money on a game they have no guarantee of recouping.
Okay, I'm sold. When can I buy?
I'm not hearing much about this game other than it is by the same guy who did the Panzer Dragoon series but it is not in that series. Not sure if that detracts anything for me or not. Loved that world, but I love the gameplay as well. I think I will be happy either way.
