People seem to get really defensive or annoyed when you ask this, which is odd. But the lack of... showing what you can do in the game... in trailers for the game, justifiably raises questions. Then you get people flying off the handle, "oh you want exp and gunzz, fetch quests and killin shit thats what you want cuz you can't appreciate anything else huh?!" No I want to know what the game is about, is there a story, what do you do in the game. I don't find any of that outlandish. Answering those questions is so tiresome for some people that are following the game more closely for whatever reason, and I don't get why they're trying to push people away from the game. You'd think people would be chomping at the bit to get people hyped about it but most responses are condescending, angry, annoyed, etc. It's bizarre.
Thankfully some people are willing to answer questions.
It's pretty obvious they need to better communicate what you do in the trailers. That is where interest for some people starts and ends. That is a completely valid criticism.
This question keeps getting asked because people see a new trailer, the game looks great, you see the transition between, planet-space-planet and it looks goddamn amazing, but nothing else is really shown... so they ask. On this here forum about games where you talk about games. They are interested in the moment but that may not carry over to tomorrow or the next day so doing a search for past threads or using search engines isn't something that enters their mind because... we're on a forum for discussing games, asking what you do in this game when a trailer just got released and didn't show that isn't some absurd concept.
