This is where i step in with corrections:
Middleage rich guy was testing a new VR-helmet, during a storm and lose lightning/thunder the helmet fries his brain but sends every info of himself/his conscience to Rustbucket.
Rustbucket is the son of a previous ex of Fiona(who still loves/loved even after having her daughter) and such Dad(it's NOT fatMC's dad btw) died. Priscilla loves Rustbucket so she is happy that he is out of the coma although amnesiac. Slowly MC recovers rustbucket's memories, and he sees Priscilla with rustbucket's feelings, kinda softening up from the greedy, depressed asshole he was when he was in his old obese body.
The the dev had shit to do in real life and disappeared for YEARS, i don't wanna know, i don't remember, i don't care(people think that reasons make a disappearance forgivable, but in my opinion it's relative because on internet everyone can lie, so i stick to "he was away/not working on the game, i don't care why, i only care if he comes back")
The he came back (yay) and we had incredible expectations...but shit goes bad fast, because the plot delves into FatMC's mysterious dead(yes his body is dead, fried brain, unable to be saved), but somehow in Rustbucket's body, manages(this is the short version btw) to find out who killed him and why(the vr-helmet got modified to make it less resistant/got fake-safety switch) and FatMC's dad is also a victim of this bad guy who is trying to achieve immortality through "being inserted into a computer and then try to get absolute power over the entire cyberworld, like supreme admin of internet with unlimited powers" and he was kinda winning, but MC was kinda trying to save everyone thanks to his dad...but here my memories are blurry, i mentally checked out and i even forgot to save, and the dev disappeared again.
