perhaps if I was married I wouldn't have this issue but I am no where ready for that.

And if you don't find a wife .... If you intend to marry wouldn't it be better to prepare sooner than later.

Six hours a day is a waste of God's precious gift. God will judge you on how you use His time. 

Doesn't sound like wisdom on the part of the priest (the 6 hours I mean). Even your use of language points to the fact that, for you, it is a problem.

Do you do any works of charity? Is there a neighbour who would need help with shopping, gardening, whatever?

Neighbours were only an example. The main point was "Do you do any works of charity?" 

Going to sleep I had strong resolutions, now upon awakening I am heavily tempted to limit my self to 1-2 hours a day... I can see why my confessor said that even if I delete everything that 'people always find a way to get it back'. I am heavily conflicted, perhaps if I was married I wouldn't have this issue but I am no where ready for that. 

That is how the devil works. Your resolution brought you peace but the devil is here to take it away. You won't be able to limit yourself to 1-2 hours, but with God's grace you will prosper if you sacrifice video games for Him.

I deleted all video games years ago and have never played them since, excluding a couple of LAN parties and a couple of browser games.

If they were installed on my PC they would be a constant temptation.

For the love of God please delete the games or you will have to learn it the hard way. 

By the way, the first few weeks of abstaining will be the hardest but it will progressively stop being an issue, especially if you find something else to fill your time.

I should add, that my confessor said that as long as I do all my duties first it would be not a mortal sin to play video games (unless it was anything impure, but that is a different ballpark). Even playing 6 hours a day would not be a mortal sin, though it would be a venial sin. I don't know if 1-2 hours a day would be a venial sin, I should probably ask him again as somethings I forget things or they go over my head in confession, but I do not want to commit even venial sins. As even that is hitting Jesus in the face.

In the OP you said: "Over a year ago I made the decision to stop playing video games in-order to be closer to God."

This tells me (and should tell you) that you recognize that playing games separates you or makes you drift away from God, which means that for you, playing games is a danger that you need to completely and immediately avoid. 
  

Waking up this morning I was resolute suddenly to delete and uninstall the game, so after my morning prayers I did. Please pray that I may continue to abstain from video games.

Praise God! 

I think for me the worst part of games is i cant just not think about the game. Yesterday i was able to limit myself to 2 hours, but afterwards I was thinking about how I can maximise the next 2 hours and be a better player at the game, even looking at information on YouTube etc. Yes I am autistic like that.

I'm the one who kept telling you to lay off the games. I'm also autistic like that and could limit the playing time but not the absolute obsession of min-maxing and competitive excellence.
The only solution was to quit cold turkey.
