I'll watch footage later, but going by most of the GAF impressions, not surprised. I knew it'd bomb.
Right off the bat, extraction shooters arent even a popular shooter game mode, so anyone wanting more action will be disappointed. If extraction gameplay was so great and popular you'd have more games like this or this mode would be in every shooter. Your closest mode is probably multi-team Search & Destroy mode (one death, team based objectives), but Marathon maps are much bigger and you got AI grunts that get in your way (like Titanfall). And in games that have a S&D kind of mode, I dont even think they are popular vs the traditional DM, TDM or basic objective modes.
The graphics were always going to be hit and miss. Bungie had to change the art style because they already did Halo and Destiny which are similar sci fi. They decided Marathon's new art to not be like that or like the typical meathead space marine setting either. So they chose a unique neon coloured and clean sci fi style with characters having a lot weird art and attachments on their face and helmet. They also tried to hype it up with those 4k high res character images trying to make gamers think the entire game is equally that clean and detailed looking. It's obviously not.
You can play solo. But there is no solo only mode. So if you want to play as a lone wolf you can, but you'll be lumped into lobbies who will have teams of 2 or 3. Bungie even stated it'd be a slog if youre trying to play as your own one man team.
They should add solo queue. Or just purposely force gamers into teams of 3. The game has 18 player matches I think. So just have servers sort lobbies into 6 three-player teams. Similar to DM or TDM. If you want to go solo, there's a DM mode. If you want to play on a team, there's TDM. Even if youre a lone wolfer like I play, I get put on a team in COD so it's not something stupid like the game is a wild west of a 6 player team vs a 5 player team vs a solo gamer like me on my own. Makes no sense.
