You can play TW2 twice and see all the different story content. Sure you can argue that you can do the same for DA2 if you speak only about how you chose to end things. Yet In TW games there are also no choice in who you play, how you play them, their personality, how you interact with the people around you...
did you even play the game or are you speacking from what you heard
1) TW2 has 16 end states so playing it just 2 won't allow you to see everithing
2) "ONLY how you chose to end things".....let's agree to disagree
3) naturaly you can't chose someone else to play as since this is his story
4) not having any choise about how to play Geralt, personality, interacting with people.....are you just troling or do you actualy believe what you are saying
In TW games you step inside Geralt and you look for your lost girlfriend, and along the way you get to make one or two big choices that change how you get there.
this makes it clear that you have no ideea what is going on in TW2, the main quest is finding the kingslayer/ clearing your name. That leads to regaining some of Geralt's memories, some of them about Yenefer
You get to chose how they respond to the world with tone or dialog. They let you chose who you pal around with. They let you chose your own path to the goal in a thousand tiny different ways that makes each and every playthrough as unique or similar as you want. TW lets you do exactly none of those things.
1) tone or dialog..... TW has that in case you are not aware
2) chose your own path....TW has that in case you are not aware
3) a thousand different ways......i wish there would be that many posibilities, i'm waiting for the hard evidence
DA is a tactical party based system. TW is a button masher.
1) TW1 could be considered a button masher, TW2 however if you are incapable of using any form of strategy sure you could mash buttons and hope you'll win or rage quit. DA can be seen as a button masher too, spam every spell/ combat skill you have and hope you'll win, or even worse a game that plays all by itself because of the auto-atack and companion tactics, you could do nothing just walk up to an enemy and your companions could kill everithing while. What makes a game like DA &TW tactical is the one behing the controler/ K&M
