1. Resident Evil (the old series) - Atmosphere made this game. It was scary, mysterious. It had puzzles, story, action, character. Probably my all time favorite series. 2. Super Metroid - Exploration, progression, boss fights! I don't need to explain why this is one of the greatest of all time. If you haven't played it, you're cheating yourself out of an experience. 3. Zelda a Link to the Past - Like Super Metroid above, it just had all the elements of a great GAME. You PLAYED it, not just watched it. They don't make 'em like this anymore. 4. Diablo 2 - "Kill, reward" - this was what the whole game was based around, and it worked. Just one more kill! You couldn't stop.
Don't lie to someone who trusts you. Don't trust someone who lies to you.
Well, my favorite game has been Tales of the Abyss for 7 years now and nothing has come close to dethroning it in my eyes, to the point where i have now played it about 6 times. But considering it had horrible load times, and subsequent games in its own series improved upon the battle system, I can't officially say it's GOAT.
