Pretty much took the words out my mouth. I tend to play fantasy games or games otherwise detected from reality. I'm not sure even EA are shameless enough to have a barbarian warrior charge at you, stop just before he swings his battle-axe, smile and then say "Drink Pepsi". Outside of sports sims and sports emulation, a world that whores itself out so constantly to the point where having no adds could even spoil the immersion, the only real way to promote things in games is through skins and themed items. Marvels Avengers was regarded as being infinitely shameless having, for example, Version Media themed skins in that game. I mean, what the fuck?
I don't mind it when it's at least done with at least some tact. For example, I started playing a game called Two Point Hospital on steam a few days back. The game is published by SEGA, who are celebrating the 30th anniversary of thier most famous icon Sonic, and boy do they want the people playing TPH to know it. You can decorate the Hospital with Sonic rugs, Sonic plants, Sonic wall art and even Sonic rings on pedestals, it's complete madness! I've also been playing Tales of Arise that's been really pushing DLC costume packs themed around what I think is Sword Art Online, then there was the free Phantasy Star 2 and Nier Automata skins in Gravity Rush 2. Outside of sport sims, it's far more subtle because it has to be, but @StaceyPowers, it IS there, more often than you think.
