100%
Having been a reviewer myself in the past, game-fatigue is 100% a thing and it 100% affects how you rate games.
If you play a game in your free time, in fits and bouts, having fun with it and taking your time, you'll enjoy it as much as you can.
If you're rushing through a game during your spare time, in order to write about it, and shirking other urgent responsibilities/deadlines, the fun quickly drains away and you start getting frustrated no matter what, and you'll only enjoy it 3/4 as much as you would under a normal player's circumstances.
