We, the players, are first and foremost, voyeurs. We watch it happen and the control we have over it is usually limited.
Secondly, we are controllers, where applicable. We play the game, we make the choices - where applicable. Needs said twice.
Thirdly, we are voluntarily manhandled. The dev is in actual control of what goes in the game and we can only flounder about within the confines of their making. The dev is Simon and Simon says... But it's third on the list because this ain't Saw, we can still quit playing at any time without consequence.
Fourth - the liberators & deliberators! By using the awesome power of money and mob consciousness. we can force some of the devs to include random shit like NTR, feet, more NTR, beastiality etc. Just like some countries using the power of freedom to instill a democratic dictatorship wherever there's oil to be had, whilst never fully agreeing on the content to be added.
And fifth, we are suckers because we suck and fall for patreon scams, terms and conditions, fbi sting operations and G.I.R.L encounters of the third degree.
Now what were we talking about?
Right, assuming direct control of the main character. That always makes me feel like a Reaper, indoctrinating innocent bystanders to seek and destroy pussy at all costs. Like an achievement hunter, i go for all the scenes in the game, regardless of story and circumstances, because how could you not?
Can anyone here play a game following just one route, limited by personality and interests, then delete it regardless of how it ends or whatever else there is to see? I doubt it.
Play the game, try everything, destroy every hole in sight.
Ok, i lied. In games with optional NTR, i tease those fuckers, then deny them the taste. I finish the game on the good/innocent route and then delete it, leaving those drooling NPC creeps forever unable to reach Nirvana...
So ultimately, it's a matter of taste, timing and mood. You can "become" the MC and fantasize if you feel like it or you can view from afar as a detached observer and maybe even guide their way a bit. You can feel the emotions by reading through the story or just laught at how poor a writer the dev is. You can go in looking for a quick fap and come back out hours later having actually enjoyed the game.
Shit happens. Move on.
