While I was sitting, thinking about what to start playing next, I was struck by how often I've been forced to change my initial assessment of a game. Whether I'd jumped the gun and simply written it off early, or I simply "didn't get it" when I played it the first time, there have been times where I've gone back to it and found that I'd been completely and totally wrong. Not always, but enough for me to shun simply giving up on a game the way I used to.
For me, the big "Ah-Ha" moment was The Legend of Zelda: Majora's Mask. I hated the game the first time I tried to play it. I was still in my early teens, and the complexity and oppressive atmosphere put me off so much I gave up almost immediately, before I even finished the first dungeon. It wasn't until I came back to it, years later, and gave it another chance. Now, it stands as one of my favorite games, and something I consider a masterpiece.
There are others I could list; KOTOR2, Sonic Adventure, Starcraft, Minecraft, among others. All of them I disliked at first, but that either grew on me as I played or suddenly clicked when I gave them another chance.
What about you? Are there any games out there that you've changed your mind about?
I believe in honesty, civility, generosity, practicality, and impartiality.
