my 20000 cents:
- Combat speed is spot on. CDPR said in many interviews that they use a real swordsman and that this IS his speed. None of the moves I saw are unrealistic. But oc there are concessions being made to responsiveness, moves blend into each other much faster, dodges are almost instant. But sitting and watching is a bad way to judge it. You have to play it. Some (and me) might argue that DarkSouls has some of the best combat in 3rd person games but you can only experience it by playing, watching a video does not do it justice, on the contrary, visually DS combat looks boring, sluggish and very unrealistc.
- Johnny is one of my favorite new additions, I love the contrast between his deceivingly cute-ish face and his speech. It is all preference
- Harpiesfight is good. I defenitely saw hitreactions and the only bug I saw was that when Geralt killed one harpy and attacked at her direction, his hits did not interrupt the "falling down dead" animation, this could be an oversight or just a technical limitation of the physics engine.
- Slowmo-bolts, hmmm, can live with it, gonna play w/o crossbow anyways.
- The old woman turning white eyes is a little cliché, I agree but I liked the whole scene. candles should move though and change the light in the room, it was a little stale but this might be changed later
- People really thought there will be a full-fledged dynamically adapting parkour system in the game ? Get your expectations in check. What we have seen is vastly superior to other games in THIS GENRE. Plz stop it with Mirrors Edge. I rather go with richness/detail of environment.
The only thing I am missing and somehow goes against CDPRs marketing of TW3 is the open world "world"

I LOVE that CDPR puts an emphasis on characters, story, decisions and different environments in their video material, it is EXACTLY what I as a fan want to see.
But having said that, it goes against the strengths of an open world/simulation. Atm it looks like "walk, cutscene, dialogue, cutscene, walk, combat, walk, cutscene.." because of it episodic nature and CDPR not wanting to spoil too much, in the interest of time, and so on.
The next thing CDPR should do imo is put emphasis on the systems and open world.
Show the awesome monster ecosystem you told us about, the random encounters, the exploration.
Kill a few bandits, let their corpses rot and observe the wildlife. Let Geralt just roam the land
(holy moly long rant thread)
