My friend started playing Prey 2017 for the first time which spurred me to replay it so we can have conversations about it. I also pretty much forgot a lot of the finer details of Prey so well, why not. Though he's finished the game before I did and I don't feel like finishing it anymore. I did play differently this time around. Previously I mostly stuck to Human ability upgrades and pretty much only had one level in Kinetic Blast. Now I maxed out Psychoshock and Kinetic Blast which I use very liberally, and also used Mimicry for the first time ever. Yes, I finished Prey 2 years ago without ever having turned into a coffee mug. So I think I got a little something out of replaying Prey.
I'm also guilty of replaying Deux Ex, Fallout 2 and some other games a whole bunch of times. With the Master Chief Collection, I've also been revisiting all the Halo games. Though with Halo Reach, 2 and 3, I only ever played co-op with my friends on their consoles since I never owned those consoles. So doing a solo run through them is quite fresh. Often times I am tired with work and stuff, want to play something and also want the comfort of familiarity which can lead me to replay old games that I have nostalgia rose tinted goggles for.
That said I do feel like, why am I wasting time reliving old experiences when I could experience something new? I guess I feel a little guilt? But like, at the end of the day it's all rather unproductive shit we do for entertainment's sake which is the mental upkeep we need to keep on going with other less entertaining aspects of life. So it doesn't really matter how you go about doing it.
