trusteft: I was with you till you mentioned AoD as the high point of replayability. I am not even going to comment that because I can't say anything without sounding like a complete ass to you, and I have nothing against you.
Anyway, to each his/her own.
Maerd: You can even absolutely hate AoD as a game, but the fact still stands that content is different for different characters. AoD is an indie game and has many flaws, obviously, but I liked the story, and for me the story is more important than other factors in RPGs. As for another example of different content on different playthoughs there's always the witcher 2, but I thought comparing mostly text based Tyranny is more fair to AoD than to the Witcher 2, which is what they call AAA.
20 hours of gaming for one way of playing the game is fine with me. At least when we are talking about story based games. As is Tyranny. Considering you can play it at least one different way, that's a minimum of about 40 hours.
For a linear RPG that's ok with me.
AoD is very different for each character, but if you take away the absurd way of handling things (only certain ways can even allow you to play the game beyond a point, if you miss side missions you are screwed, etc) I really really don't see how it can even reach Tyranny.
If I want to play 100s of hours of a game, if not 1000s, I have strategy games for that. But, to each his/her own.
