Grinding is rare in most modern games beyond RPGs and Multiplayer shooters (to add perks and such). Micro transactions merely gave game developers an excuse to add more.
And don't worry, I don't buy games that use F2P models unless they're reasonable (eg. Cosmetic upgrades, new weapons, new characters, or new content in general). The problem is that there are legitimate interesting games being bogged down by poor implementations of the F2P model. They add excess grinding, tons of in game notifications, and generally ruin game balance.
F2P models can be alright if executed correctly, but the examples from These launch Xbox One games are just bad (especially since most of these are full game prices). I'm really hoping these poor implementations of micro-transactions don't stick.
