Majong Scrolls is another F2P collectible card game happening out there, though it's hard to say how long it will stay in beta. Plus you've got last year's Card Hunters which was huge at PAX, they have been in Beta for about 3 months now.
Add in the Blizzard announcement and it seems as though this area is going to become quickly saturated.
Playing with what you got in order to get something you want and playing with what you got in order to get something random are 2 totaly different things.
A Mechwarrior game should give the pilot/commander the option of what equipment they want based on how much resources they can afford to spend on it; like the Mech Commander and Mechwarrior Mercenary games.
This random crap is just that. Crap, and the reason i wont drop money on it.
That's the beauty of it being free2play, you won't have to drop any money on it. I completely respect peoples issues with collectible games, but it's something they decided about MWT very early on and I don't expect it to change. The good news is you'll have the opportunity to try it out for free.
Does that mean you'll like it? Who knows? Every game has people it doesn't appeal to. At least you can figure that out relatively easily with a game like MWT.
What I noticed with Balu0 and my own account, watch for the founders icon in your posts. It gets added to old posts that you've made, once you get the founder's icon it seems to indicate it's gone through.
