I do not like the unbounded nature of the freeium pricing model (same is true for the subscription model). I am willing to pay a higher, one-time price for a good game or even for DLC, but as a matter of principle I will not pay for the small but unbounded loot packs or coin packs of freeium games.
I'm surprised that more mobile game developers chose the freeium model over the single-purchase pricing model that works for dedicated gaming platforms.
