I keep really really hoping that The Witcher becomes this for me, I've heard about what an amazing game it and it's sequel are, I bought both of them, I've heard how mature the storytelling is, how awesome the setting and the choices are, but at this point I just want to ask someone to give it to me in novel form because everytime I play I get frustrated with the controls and never get anywhere.
The biggest example I think was Final Fantasy XII, I think I was one of those very few Americans who actually bought Dragon Quest VIII because I wanted to play Dragon Quest, but it had a free FFXII demo in it, which I played briefly and quickly cemented my disdain for all PS2 era Final Fantasies (Damn you X, damn you!) Then on one bored afternoon I decided I'd just give it a whirl because I had fuck all else to do and somehow... strangely I felt compelled to keep playing it... then less than a month later I plop down money at Gamestop for it and it goes from originally being "Gah Final Fantasy is dead" to "This is the best Final Fantasy game I ever played EVER!"
I think the combat system is what originally through me off, it at first glance to an outside observer looks ridiculously convoluted and needlessly complex with it's use of color arcing lines and strange looking license board. Once playing it though it all became very easy to pick up and get into, and in my mind was tons of fun, it was the first time in a long time I actually had FUN grinding in a JRPG.
