To be honest i could not choose my top 5 favorite games of all time out of he blue but i will try. Ignore the essay after each entry if you want :p
1. Majora's mask as a kid I always loved this game I try playing this game right after I beat OoT and since i had a japanese copy of the game well i was completley and absolutely lost on what to do it took me 3 YEARS to actually beat this game you might laugh but is true, because of this i share a deep nstalgic feeling with this game the same way the pokemon anime is nostalgic to a lot of people.
2. Final Fantasy 6. It's the best period. Great story, characters, villain, gameplay it had it all and this isnt a bias opinion either i have no nostalgia for this game and yet it holds as one of the best I've ever played.
3. Persona 4 by god what a game much better than its prequel and in my opinion best game on the ps2.
4.Metal Gear solid 4. I had a tough time deciding between the 3rd one and this one but i decided to go with this one because well I was crying to most of this game it was just so well written and had great gameplay to boost it all up, the end of the game is by far the best ending to any story that i had ever read.
5.Pokemon Platinum. To this day i still don't know why people hate the new gens of pokemon so much, I've played the pokemon games since the johto days and I still believe that this game is just better than the other though it might be debatable i still think its an amazing game, as of now i have 105:78 hours of gameplay time that is an achievement that few games have ever done.
