Put simply, I like microtransactions if they add small and meaningless items like cosmetics. I don't like microtansactions when they lock content/make it impossible for someone to play without them (e.g. powerups like XP buffs or microtransaction-specific gear/weapons).

DLC content is a tricky one for me. Sure, I'll buy DLC if its meaningful for the price and has actual content added to the game, but I'm not a fan of burning a whole in my pocket for items/objects/maps/etc I'll probably never use/play or get to use/play.

I miss the golden age of expansion packs. I used to play games like BF1942, Age of Empires, or even games like WoW relentlessly because I saw replayablity simply because the content was numerous and there was much I could do. Now I hardly play through games more than once or I'll get bored because I don't find anything worth my while.
