Blood Bowl is fun in the concentration risk management sense. id reccomend it for the classic mode alone. Chaos edition has 3 more races than dark elf edition but its compatible either way. There is alot of satisfaction in making the risk work more in your favor though occasionally the dice will be absolute ♥♥♥♥♥ though like a halfling punches a minotaur and somehow wins Killing the minotaur. O_O It is a fun game and pretty interesting :) a definite reccomend from me.

There are limits on the free to play part of TF2 though

simply download this week and play free for all time I think. besides valve does still have the ingame shop to still cash in on
