In my 12 hour playtime here, I've completed the campaign on hard, finished 2 hard-mode skirmish matches, a few difficulty 10 wargames, and at least 1 hour of idling.
Go buy the old games. Usually about 5 USD. They won't look as good, but you'll have games with better mechanics, better written story, more ship variety, multiplayer worth a damn, a bigger community, and a library of mods to keep it all interesting.
As a Fig backer, none of the promises were kept. Literally none of them. The scale didn't get bigger, the ballistics mechanics are nonexistent, the railgun frigate is gone, and the scarring system is not only irrelevant due to the average ~15 minute session time for each mode, but also completely nonexistent. Instead, ships show a gross tiling effect for damage. That's every feature they mentioned in 5 years of "insider access", just not in the game.
From an RTS standpoint, this is worse than "Babys first RTS". There's no strategy here. You blob up and smash your blob into the enemy blob. Just watch any video showing combat. Capital ships don't move. There's no evasive maneuvers or any kind of action. Strike craft do ovals, don't even try to dodge fire (cause its not ballistic, so its not able to be dodged anyway) and still care more about maintaining formation than fighting the enemy. Everything responds so slowly and moves so slowly (except the mothership, which is the fastest ship in the fleet somehow) that it is impossible to apply any tactics. There is no hyperspace mechanic anymore to make up for it. You're sitting there hitting timer abilities that just make your ships better until one blob kills the other blob. Its braindead gameplay, and the rosters of available units are too small to make up for it. Tech is linear, so the overall progression of each match stays the same. There is no room for different builds. You tech up and try to out-rock-paper-scissors your opponent before the resources run out on the minuscule maps.
From a Homeworld standpoint, nobody asked for this. Is Homeworld a game where you expect hyperspace wizards? Hopefully for your own sake you answered yes. Beyond that midichlorian-level of lore shredding, it amounts to a child's fanfiction. Imogen accidentally falls into solutions for their problems, or just straight up knows what to do at all times. The Incarnate Queen forgets that she opens portals that spit hellfire enough to destroy planets, and lets you walk right up to her. She throws a temper tantrum upon losing, told to us through horribly amateur cinematics. Only to be forgiven for her killing of millions of people once they realize she's just lonely. The story is so pathetically weak that none of the descriptors in any language can properly describe it. The lore has gone through a mulcher. It contradicts every single game in some way, including BBI's own Deserts of Kharak. People get hung up on the character focus. I don't even care that the narrative style switched. The characters they focused on are just categorically stupid and uninteresting.
This game is a regressive failure at every single possible point of measure, except graphically. The game is a beautiful failure. 20 year old games literally made in garages have deeper mechanics, better stories, and even just more things to play with. Its worse that those 20 year old games are in the same series, and the people involved in making this game couldn't even glance at them to make this remotely fit at all.
Don't buy this one. Go buy the other games in this series and forget this one exists.
