I'm not sure if I missed something, but the Remastered says that you will receive access to 1 and 2 classic. I don't have a download for them or the games in my library, so are they going to be released at a later date or is it just part of the Remastered download?

They're included in the remastered installer. You have to choose them from the game menu when you fire up the game.

Watched a youtube & I still don't get it.
What's to love I mean I bought the complete AI war series and then went 'unit spam against an overwhelming enemy that your basically a joke to?!?'... well lets say it never panned out for it.
I mean I can play Supcom alright, but I'm not getting what even 'might' be enjoyable about homeworld.
From what I can tell it's essentially a convoluted spam game of rock paper scissors on a full screen minimap.

But... The entire point of Supcom is to construct an infrastracture that supports you spamming units at the enemy. Homeworld is loved primarily because of its to this day very unusual mechanics (no, it plays nothing like AI wars and as opposed to SupCom, it focuses much more on constructing a force using very limited resources to deal with your opposition, spamming units is a surefire way to get yourself beat) and fantastic, extremely engaging storyline.

Thank you for the responses! There are only a few good mods playable for the remastered, but the classic versions have a bunch of good mods.

That's also a beautiful soundtrack in the original, which was butchered in the remaster. Partly because some music licenses expired and partly because Gearbox was unwilling to pay to renew them.

Also, missing from the Remaster Collection is Homeworld 1 expansion (Cataclysm), expansion which many think it's the best game in the series.

Oh damn.. can't those be imported in any way?
(eg: replace files from classic to remaster)

. Mm.. should I just play the original?

You should. Some of the changes in the remastered edition were not exactly welcomed. The game is harder than some people suggested and it's not a rock, paper, scissors affair. As someone pointed, thinking like that will ensure a quick failure.

If you can find somewhere the original games (Cataclysm included), you should have any trouble playing them.

You mean the credit roll song? Everything else is in the game, just not necessarily in the standalone soundtrack you can buy from Gearbox. I'd say you shouldn't. All the major issues with remaster were fixed, as far as I can see it's the superior version. Alternatively you can just play first two missions of each and decide based on that, you'll have them both installed anyway...

Essentially, Classic has fighter fuel and it's easier. Remaster is more challenging, has improved UI, higher draw distance, it's prettier (subjectively), pacing is somewhat faster, it has a ton of convenience features added in (for instance, at the end of each mission, you don't need to wait for extremely long periods until your harvesters mine all resources on the map - they get auto-collected when you opt to end the mission. Alternatively, you can wait and mine if you wish. It's optional.)

Uh.. lol.

These are changes that, to my knowledge, weren't welcome:
- Homeworld Remastered lacked ballistic model, as in, instead of simulating projectiles flying from ships to their targets, it just used RNG to determine hits or missed. This was fixed in version 2.0 available on GOG

- Formations in Homeworld Remastered used to not work properly, which was again fixed in version 2.0 availible on GOG

- Tactical settings for your craft was lacking in Remaster, it's now present in 2.0

- Fighters in the original Homeworld had a fuel gauge - IIRC your fighters needed to routinely refuel. It's a feature which sounds extremely cool on paper but ends up being a huge hassle and got removed in Cataclysm and subsequently Homeworld 2 and Remaster.

- Difficulty scaling was milder in the original. Contrary to popular belief, both Homeworld Classic and Homeworld Remaster get more difficult as your fleet increases - thing is, in Remastered version, this effect is a lot more visible and subsequently, the game is more difficult. Which I believe to be a good thing, because frankly, if you played the original decently, about 1/3 of the campaign was absolutely primitive in its difficulty.

- Combat is faster. Ships generally take less punishment before they go down. Again, this is a change I personally welcome as I always found tiny fighters taking a ton of punishment before going down extremely weird and some combat in the original had a tendency to drag.

- There are also other changes - voice-acting got re-recorded with different actors, but VA in HW1 and 2 was not really the strong suite anyway (it was a lot better in Cataclysm, alas...) and music got spruced up. And then of course all the changed cosmetics.

All in all, if you've never played Homeworld before and don't have nostalgia goggles, it's very likely you'll enjoy Remastered version a lot more than the Classic version, if nothing else purely due to spruced up visuals and quality of life features it introduces. As I said tho - there's no reason to take anyone's word for it. First two missions are about 40 minutes, just try them in both versions, preferably Classic first otherwise your judgement will be clouded by sudden loss of quality of life features. And there you go. Either way it's probably the best RTS I've ever played so enjoy!

Didn't they gave up on fuel, tactical formations and ballistic projectile simulation?! And the LAN option was removed from the remaster, too. Also Cataclysm is still missing. So, ermm, yeah...not sure if i buy the fact that the remastered editions are better :)

I can be wrong, of course and Gearbox reintroduce all those things through patching.

Just wanted to second Fenixp. Loved the original and right now I am really loving the Remaster though I haven't gotten to any of the brutally tough missions yet.

Hmm...looks like they did solved the main problems. I do like meself a LAN party from time to time, but not a fan of online playing.
