In the Direct (and other footage) we've seen quite a collection of different weapon types and ways to engage combat. Pistols, rifles, shotguns (and the different ammo types), melee weapons, fists, a couple of shots showed a dev playing primarily with explosives.
What kind of weapons are you planning on using? Often times I try to stick to one/two weapons (depending on the game and skill-system), but I can see myself at least trying out every different kind I find on my first playthrough :D
What about you?
Oh, I just noticed I forgot about space combat - tough I'm not too sure if it makes any difference in gameplay, or if it's more a "use weapon type X to attack their defensive element Y" until you can board/destroy/whatever?
Damn, 10 minutes ago I commented on not pre-ordering. Now I'm struggling myself, lol. This looks very good, and from all the tiny tidbits you can see, they overhauled the RPG systems (weapon stats, perks/attributes).
To add to this:
The only thing you're getting by pre-ordering is a car. If you're paying the game normally, you'll end up with a plethora of cars and bikes already, so you're not really missing out on anything special. (which, tbh, is decent on CDPR for not banking on huge FOMO)
You can always wait for the release and look up reviews and (more importantly) first hand player experiences on here/reddit/youtube/wherever you consume gaming media, to avoid spending money on a potentially subpar product.
Just a disclaimer: I'm also very much hyped for the DLC, and plan on getting it day one (if all goes well), but I'll wait for reviews and impressions first. :)
