Wide as an ocean, deep as a pond is a phrase dem Youtubers are throwing around.
It looks like it's more fun to move around than in Destiny, at the cost of basically having no interesting verticality to it. If you want to be reductive, there's essentially little difference between it and Destiny in terms of what you do: go to a place, some guys spawn, you shoot them, go to another place, etc...but Anthem seems to think that flying through huge caverns or gorges is enough. Destiny levels weren't amazeballs but there's variety in the looks and the layouts that managed to impress me. (The first couple zones anyways, the rest started to get very samey.) What little I've seen of Anthem, everything looks pretty samey. Pretty! But samey.
Melee combat looks more fluid than Destiny though, by half. But it's half as good as Warframe, since it appears a lot of melee is canned animations designed to be launched from being airborne.
There are also complaints that mid way through the story, story missions get put on hold so you have to do some serious MANDATORY "free play" collectathons/achievement whackamole so you can progress through the story. Everything from "Kill x enemies using every method in the game" to "hunt down collectibles" to "rez teammates X times." Pretty goddamn bizarre considering most games relegate that stuff to daily quest grinds or strict achievement farming. Anthem be like "yo dawg, can't finish the story until you do all dis."
Frankly both games are flogging a dead horse IMO, that is the MMO-lite 3PS. Once the novelty of the enjoyable movement mechanics wears off, people are saying there's not much else to hang your hat on.
And this on top of all the normal AAA big game woes. I think they've solved the server disconnect issues. But major quest bugs, ill-conceived matchmaking (lvl 3 players joining the last boss fight of the story, for example), umpteen million loading screens, a shit and lifeless hub, leaked MTX schemes where skins are going to cost $20.....given all that, if it doesn't sound like a trainwreck, it at least sounds like a "give it 6 months to pull its head out of its ass" kind of thing. Just like Destiny. Plenty of people are enjoying Anthem I suppose. But it's not the "anything" killer. It sounds like 20 to 30 hour of play before you're out of things to do. And if Destiny is their guide....whatever comes next is going to be as equally bland and repetitive.
