Here we go. For the last couple years, I've been in love with a videogame. Final Fantasy. Everything about it I find holy. I literally worship it. I've never prayed to god properly but I do pray to Final Fantasy. I imagine going around with the people from Ivalice and Gaia. Whatever I do, I just feel it nowdays. It makes me feel really happy, cool. How bad is this?

It sounds like you've left the real world in favor of a silly game. Why? Do you just like watching the numbers go up? Creating strategies? Collecting items? Completing objectives? Exploring new areas?
Sounds like you've got some problems there. Take the skills out of the game and use them for some real world stuff for a change.
It shouldn't matter to you what any other idiot thinks as long as you love what you love, Thats all that matters. ;)
It's perfectly normal :)
