I have nostalgia with most of the games but For me its RE2. I remember i was about 9 and it was the first one i beat and i played through all four scenarios by myself. I was determined not to get help from anyone and it took me a couple weeks but i finally did it. Can remember it like it was yesterday, if anyone went near the ps1 i screwed at them, i was just so determined to beat it alone and when i did i remember my dads reaction, he couldnt beleive it lol. I also remember that huge aligator was the thing that scared me the most. I picked Leon first cuz i was 9 so i had to be the man lol, and then i played claires and found it much harder, but i remember enjoying claires story the most. I was absoloutly captivated by the game, the story, the birkins, cheif irons, that classic police station music, and i just loved playing all the scenarios to see how things changed like having kendos gun shop in scenario A, and seeing how his dialouge changed depending on whether you were claire or leon and seeing how the burning helicopter got there in scenario B.Then i unlocked 4th survivor and was determined to get through that too, which was the only time iv ever managed it lol then going for the secret key from brad to get the costumes, just so much stuff. Bare in mind, the game you have the most nostalgia with dosent have to also be your favourite. Like the one i have the most nostagia with is RE2 but my favourite is REmake.
