With the PC version of Assassin's Creed 3 on the horizon, I've got to say that it may have interested me. I'm thinking of buying the games on PC, so I'd like to know a couple of things:
How are the graphics?
What is the options menu like?
How does it handle with Mouse + Keyboard?
Rebindable Keys?
Can you play it with a Gamepad (just in case)?

If there is a website that can tell me, you can just link it

Thanks in advance

The AC creed games are probably amongst the most visually pleasing games ever made.

But I played them with a gamepad, so I'm relegating the rest of the questions.

Only played the first game on PC

was really pleased with the port, controlled very well with mouse + KB

No idea about the other AC games but people say that they are "pretty much the same"

All AC games look good imo. I played the first, the second and Revelations.

The control with keyboard and mouse is really good. I have a 360 controller but didn't feel any need to use it so I can't answer about how it handles controllers.

They're fine. Use a pad if you're sane.

I prefer mouse+keyboard. It's much more precise.

I've only played the first one, but the port was quite good, and controls worked well with a keyboard & mouse. Graphics was better than the console counterpart, but that is to be expected. The first game in the series is not great though, it is too repetitive and it just feels like squandered potential.

Yes, I do. Specially when plataforming. I don't see the benefit of "analog movement" when I can do the same (and better) with mouse+keyboard.

What Alexrd probably meant is that free running is much easier (and indeed more precise) when using mouse&keyboard.
Plug in a gamepad and try to rotate the camera while traversing rooftops in "high profile mode" (in order to jump, you need to press two buttons at the same time) - it's pretty much impossible.

AC is no Devil May Cry, a controller is not mandatory.

Not mandatory, no, but more well-suited. I love me some mouse-driven camera, trust me, but this series, like Batman and Tomb Raider, is too gamepad-focused to really work as well with KBM. The AC dev team even said that themselves.

The AC games look and run great on pc. The Keyboard and mouse controls are surprisingly good. I would recommend them. The story is quite fascinating, I cant wait for Ac3 myself. :)

They fixed the controls? I tried playing the original AC with keyboard and mouse and it did not work well at all. I ended up buying an XBox 360 controller to play FO3 and found that AC was a lot more fun.

I'm not sure about latter games, but I think the AC series is GFWL, so an XBox controller should work perfectly.
I found the game to be borderline unplayable without a controller. But, that could just be because of my hands. I've got hypermobility problems in my fingers, so games like this cause problems.

The game permits you to play with just keyboard and mouse, but it's not IMHO intended for you to do so. It's just that they don't require you to run out and buy a controller if you don't have one.

Thanks for all the responses everyone, you guys are great!
