Had a chance to play a bit. You have a hub area where you can get (or not) missions and some side-missions, most with optional objectives, but it does not feel all that different from original. Slightly less linear, but not impressively so. Story is still quite fun, and the dialogues are good.
However, neither interface or combat has been improved, and it seems there is more combat now. Or maybe it just feels like that because of how boring it is. I like turn based combat, but you lack options, and the interface is frustrating, which doesn't help.
Worst of all, game is a buggy mess. You can finish a quest one way, and still have conversation as if you chose other option. Dialogue is wrongly described (e.g. option that is locked because you need skill A at 3. But you have skill A at 3). Once I was supposed as a side quest leave some guy alive, and I let him escape, only to have every NPC talk to me as if I killed him. Got stuck and had to alt-f4 when got booted from matrix. Etc, etc.
Wouldn't recommend right now.
