What? If there's one thing the Witcher games have, it's a strong emphasis on player choice and consequences based on those choices.
Or am I unclear on what you're saying? Because it sounds like your complaints are the exact opposite of what the Witcher games actually are.
You are correct, Witcher 2 does offer you more choices from an RPG perspective and there real influence on the end game then any RPG I have played
I'm not referring only to when choices carry over, but that is a big part of it. But most choices made in each individual game have an immediate effect but nothing long term, with the one exception in TW2 that you pointed out. You just don't have much influence over the story compared to most RPGs, no influence over other characters, and there's only one playstyle in TW2. Good games, but mediocre RPGs at best.
Honestly Rhamnetin have you even played Witcher 2?
I don't know a single RPG I have played where you have the option to not have some final end game battle with the antagonist that during the game you are hunting. In Witcher 2 you have the choice to not fight Letho, it would be like not choosing to fight the Archdemon in DA:O.
You can criticize the Witcher game in other areas but to say you can't make RPG choices is just silly
Played it twice. So TW2 is the best RPG because you get to choose whether or not to fight one particular battle? Now that's just silly. How much does a ticket to this make-believe world cost?
