First of all, I'd like to point out the Conversation Wheel was the deal breaker for me.
I understand (Bioware's logic) why it has shown up in DA2. People have been praising it in ME&ME2. However, what Bioware missed is that in ME it worked as a part of the whole and sometimes you can't just strip one thing from working game, put it in another and expect it to work. ME has very strong character and storyline, supported by movie grain as well as outstanding voice acting of female Sheppard which allowed me to enjoy the game in "cinematic" way and I accepted that (I will 100% buy ME3).
However what Bioware missed is that people weren't buying DA:O because of conversation wheel in ME (at least I wasn't). If I look back at DA:O, it's pretty much a generic RPG (elves, dwarfs, big apocalypse, ect.), but it reminded me so much old RPGs (Planescape: Torment, Mask of the Betrayer, KotOR, Icewind Dale) that I was able to enjoy it.
For me good RPG is evaluated by the degree I can link and embrace the character I play (it's Role Playing game afterall). Some games do it through atmosphere (Fallout), story (Planescape: Torment), dialogues with party characters (Mask of the Betrayer), ect.
With the dialog wheel, I no longer have the direct control over what the character would say, giving me "the cinematic experience". And in cinema, how often do put yourselves in one's place? More ofter people are spectators, granted, on the scene, but still just spectators, stripping away the role playing part.
Dialogues have always been core part of every good RPG, allowing people to decide exactly how would THEY answer (the picture posted above is sadly so true) through diversity and often surprising options. Hell I remember myself going through the conversation with Ravel about 7 or 8 times the first run, just to understand and try everything.
Since the conversation wheel no longer offers what I listed above, for me personally the game is no longer a RPG, but more like "Action Cinematic Game". And for similar experience I could just go to cinema with my friends and enjoy it more.
Saying that, I will be very, very cautious (and maybe upset) every time I see the conversation wheel in any other game.
