Some times I don't even finish them, because I decide I have to do certain things before that. Which I don't end up doing.
But when I do finish games I like, it can be a positive, negative, or bitter sweet feeling, depending on the game.
Some times I'll miss that world and the characters, knowing that I probably won't see them again. Other times I feel like I've had my fill of this world, and it felt like a good time to say goodbye.
I recently re-visited a world and characters I really liked from .hack/G.U. in the new vol. 4 sequel, over 10 years after I played the original. And it was an interesting experience because I felt very different about a lot of things than I did before, and it made me wonder if that was because this volume received a lot less development time, if the town always looked this empty but I just never noticed when there was no HD, or if it's because it's actually made to be more empty due to story reasons, etc.
Been thinking of making a thread about it at some point if I can formulate my thoughts better.
