Just an idea (not exactly a good idea but here it goes) about business model practice on gaming lately (especially on mobile games).
The system that nickel and dimed you on the things that necessarily to progress the game. And the overpowered items you only get
to pay for. And the timeout system that prevented you to play more. And crucial story chapters or characters that have been sliced out
to make DLCs. And Confusing in-game currency system.

Just take my money and give me a completed experience !(or at least for good amount of it)

p.s There still are reasonable Free to Play games out there that make you want to pay to support them. good system supported by
cosmetic items and services that not destroy the balance of the game. or reasonable DLCs that give you fair amount of "content" they
have promised.
