I'm... hopeful. They have the tools to create something truly worth playing. A cause for concern is they're locked into a 10-year contract with Activision already for this. The chance of this being some hardcore AAA bullshit is very real.
The concept art looks rad but I've heard a few times now that this is supposed to be "less serious" than Halo, and Halo was already pretty damn goofy at times. SO I'm kind of at odds with these pictures, I can't help but imagine just on the other side of that battle tank is a juggling gnome.
I'd recommend reading Polygon's article, it does a pretty good job of going over everything. From what I can tell, they plan to make it pretty seamless, with no loading screens and have multiplayer be like Journey's where players will just show up and what not.
So the alpha is out and despite not having a lot of content I would have to say this game is really good. The strike mission they have in the game took a solid 2 hours to complete and felt like raid/dungeon bosses of mmos were used for the bosses this. The story mission you play is ok but obviously just a taste. Pvp multiplayer is pretty fun as well but strike missions are the best part.
I'd say I'll play it with you, but I don't trust you not to flake out on me and never pick it up or pay for online. Or anyone, for that matter. I've bought a handful of games in the last couple of years, because people said they'd play them with me, then I get excuses from them on why they didn't get said games upon release. NO MORE.
With Sony's heavy marketing of it and sly and largely untrue, "Play it on PS4 first," line, I'm sure most people are. Which means I'll be, too. Only makes sense to go where the people are in an online multiplayer game. I mean, unless I'm just absolutely apathetic upon release, but I'll probably find some reason to buy it.
