I never played Homeworld, should I?
Homeworld 1 is a storyfag & graphics whore's RTS. Unlike games before it, and most games since, it really did play out in a 3D space. And in multiplayer - but only in multiplayer - the full 360deg mobility actually did have an impact on gameplay. However, I strongly doubt anyone can say with a straight face that the primary benefit wasn't visual appeal. Homeworld 1 was awe-inspiring to look at when it came out, and its proper 3D movement had a lot to do with it.
Basically, it was an amazingly pretty game that told a genuinely good story and told it well. And it sounded almost as good as it looked.
However, a lot of the mission design was fucking awful, and the unit balance was a complete clusterfuck.
Homeworld: Cataclysm looked exactly the same as Homeworld 1 (same engine, so no surprise there), and it tried and somewhat succeeded at addressing Homeworld 1's gameplay issues. Unfortunately it failed miserably to deliver on the one thing that ensured Homeworld 1's place in gaming history: storyfaggotry.
Homeworld 2, as others have noted, had the second worst story in the franchise. And while it really did improve a hell of a lot on many aspects of the original, it also managed to streamline the gameplay significance of 360deg mobility out of existence.
I would definitely recommend playing Homeworld 1 for the storyfaggotry. And if you like it, especially if you like it enough to play a match against a friend, I'd suggest playing Cataclysm too. Homeworld 2 I'd suggest if you like
Chris Foss and think it'd be neat to see his style of stuff getting blown to bits (and who wouldn't?).
Well, GalCiv2 was an incredibly boring game so...
I'd love for someone to explain that opinion to me some day. GalCiv2 is in a lot of ways a streamlined version of Civ2, set among the stars in a very silly future. The AIs have unique dialogue and much more distinct personalities than any Civ have had to date. The game has a fair pile of random events and a karma system that despite being primitive affords genuine roleplaying opportunities. It has as good a difficulty curve as Civ - meaning just about as good as it gets in the genre - and some of the best AI in 4X-dom.
Sure, it also Tech MK.V, RPS'y space combat and even more primitive ground combat. But if that's why people call it soulless & boring, why don't the same people say that of Civ where combat is even more shallow and every damn city needs to spam the exact same string of units and buildings, except in a very few, rare circumstances?
I can totally understand hating GalCiv2 if you've only played with ToTA, or the genre just isn't your thing. But if you like Civ & -clones, then the boring & soulless comments that always get flung at it around here are... More than a little bit strange to me.
