Origins is one of my favourite games of all time. If you loved Origin for its combat system that's not what you're going to find in Inquisition. I've been playing the game for about 10 hours on PC and I play at the Nightmare difficulty with friendly fire tuned on, just like I love playing Origins.
Story wise I haven't really experienced that much in 10 hours, but I have a feeling that they're trying to be modern by making sure to include all sexualities, genders, etcetera. That's something I'm fine with and so far the story, even if I don't really find a civil war between mages and templars all that interesting, is quite all right.
I have always been someone that greatly enjoys good game play mechanics and tactical combat. In Origins I played every battle in the tactical view and micro-managed almost every attack in the fight, for every character in my group. This made every battle take a while, but they were generally really well balanced and really fun to play.
What you should be aware of is that Inquisition is, in my opinion, more of a spiritual successor to Origins than a proper sequel. The game has clearly been designed with the action oriented console player, rather than the pc strategist (neck beard?), in mind. You no longer get to allocate your stats manually, the ability trees have been more streamlined and combat is generally flashier and quicker.
If you're playing the game on PC you'll quickly notice that the interface was designed with a controller in mind, for example the tactical view is centred on a cross-hair in the middle of the screen and can only be manoeuvred with the "WASD"-keys, you can also not loot items or talk to people simply by clicking on them and having your character automatically run up to the item/person, but instead you must manually get in range before clicking on it/them. The last thing might not seem as such a big deal, but it does become a bit annoying when you have a lot of things to loot.
Furthermore the tactical view is a bit broken, partly due to the controls, but also because you cannot zoom out enough so you get that same awesome overview you had in Origins. Another note is that if you're in a cave or in a building the camera will "hit the roof", i.e. you cannot zoom further than the roof and you are basically stuck a meter off the ground. The issues with the tactical view are the biggest gripe I have with the game, as I basically spent the entirety of Origins in tactical mode.
- Can you enjoy Inquisiton on PC and could it even be better than Origins?
I'd say that it depends very much on your play style and who you are. If you're like me in that you love strategic, difficult and a bit slower paced combat and that's what made Origins for you, then no, it won't be better than Origins.
If you on the other hand don't mind sticking to that third person view, playing on a bit lower difficulty level and having the AI control your group mates as you whack away at your enemies with explosive and great looking fervour (The game is really good looking and the sliding animations are fantastic!) almost enjoying the story more than the game play, then it's definitely a game for you. I also see no problem in playing the game in the third person view on PC, it's only the tactical view that's a bit broken.
Myself, I'll most likely get through the game and I'll most likely do it using the tactical view as I don't really enjoy the hack'n'slash side of things. If the tactical view gets patched that would probably make the game rise quite a bit in my eyes.
There have been some questions raised regarding it being a "single player MMO" with a lot of quests using the formula "Fetch X of Y by killing Z!" and I can say that there appears to be a bunch of quests like that, but I haven't played long enough to really form an opinion of that just yet.
The above text should not be considered as facts and is only my opinion of what I've seen so far in the game, i.e. my opinion might change later on and I'll try to update this post accordingly if I remember I ever wrote it. Take it with a grain of salt and it can hopefully give you some insight into what the game is like if you're the kind of player I am.
