StingingVelvet: I'm waiting to play it until actual release, but seems like the scope is pretty limited in general?
Depends on the area. Darwin Village is considered a minor location in WL2 although it's definitely a major location in WL1. Major locations like AG Centre will probably take a couple or a few hours to go through. There's also Highpool, the Prison and Interior, Canyon and Temple of Titan, and Damonta in the current build, those are the major locations and if you include the minor locations you'll clock quite a number of hours to end the beta from start to finish, I'd say 30 if you're a completionist. I haven't done Damonta myself, looking forward to it. Arizona is around 40+% of the game? The other half L.A. will make up the for other 50+%, so the estimated ~50 hour gametime by inXile is most likely true. Although I can easily make it 70-80 hours for a single plathrough if i want to.
My problem with the beta so far is that some of the quests in certain locations are rather bland. They don't involve a whole lot other than being a glorified fetch or kill sidequests. There's nothing too compelling about them that makes you wanna explore something or finish to find out about the plot or backstory. You're told right at the start what to do and you just do it. Quite a number of locales that could have so much more potential, ends up being a 1-task sideshow. Of course, the major areas are more involving, the Canyon and Temple of Titan areas have alot more to them and have factions you align with. You have a choice to save both AG Centre or Highpool at the start of the game, and they have consequences, I've done AG Centre and Highpool like 3 times now since last year. I can't comment on Damonta yet. Whether you'll like the content in the the major areas is another thing though. For me, I have mixed feelings, I like some of them and I got issues with some. L.A. looks pretty darn awesome compared to Arizona from what screenshots and info they have released so far. Not sure how it compares but we'll have to wait for the final game to judge.
