I'm halfway there in the campaign, and honestly, it's a great game if you liked Homeworlds.
-the unique art direction is there
-the gameplay is very like Homeworld, and you will feel immediately at Home (ah ah ah)
There are annoyances, however
-No autocollect and automatic mission end. This is coupled with the existence of a ''rare'' ressources and artifacts that have to be collected to improve the ship (IE, you have to hunt every single thingy before completing the mission, which manage to be more annoying than Homeworld One ''painfully slow collect'')
-Heavy rely on mission triggers (cue to the trademark ''must destroy that ship that is not spawning...'')
-Don't even bother with lower difficulties
As I paid for remastered and got a sizable rebate on STEAM, I find the game worth his money-but that point is going to be discutable for people that don't like Homeworld, because it's a bit barebone ATM.
