I'm unfamiliar with a few of the terms you've used. Like I said, I am completely new to this mod xD
By SMAC do you mean the MAC Stations? Or something else entirely? I've been using the MAC Stations my worlds in such a way there are no blind spots and multiple killboxes. I do however also make use of the Anchor Stations due to their ability to repair ships should a repair ship be lost somewhere, their ability to stop the planet from being lost whilst it is still up and the later unlocked Slipspace Gate.
The main thing I find problem with is gaining the funds needed to start production on fleets, be it credits, Titanium or Derilium (Is it spelled correctly?) I've been pushing to get the Infinity out quite early as a suitable addition to any fleet be it small or large.
Yeah, the SMAC is the MAC Station or ODP (Orbital Defense Platform). It's your big stick. Now, you don't want to spread your ODPs out. They are MUCH better in clusters. If the enemy wants to sit in a corner of your gravity well and watch you, that is great. They can do that. Now, what Sternus is apparently utilizing the Anchor for is, well, literally as an Anchor. I'll go into detail since he didn't. The Anchor has an Orbital Government skill/ability that prevents the orbited planet from being purged of your forces through orbital bombardment. Instead, they need to blow up your Anchor station as it has your planetary officials on it. This is undoubtedly a good strategy. Next, you want to layer your SMACs around this Anchor (also, preferably place the Anchor as close to your planet as possible) in rings, preferably layered. The size of the rings don't matter. This becomes a killzone of doom. Of course, this is super expensive and is really hard to do at any point but late game, which is why I deem it "expensive and time consuming". Resources, it's really luck of the draw. Usually games come down to buying off of the black market but sometimes you'll score some awesome planets where you can get a ton of resources off of them. It's a hit or miss, really. Rushing Infinity is generally, in my opinion, a really bad idea. The ship itself isn't that great at taking on whole fleets like it does in lore and is more of a single target killer. It is also ludicrously expensive and takes forever to build. You're better off building a lot of shitty, cheap ships than one big target. Infinity is only good with a supporting fleet otherwise it gets eaten alive in fleet battles. But again, building as many trade stations as possible is a good idea. Prioritize the economy techs (top of the civic tech tab) and dedicate planets to certain purposes. Make some military/production, some frontier and thus volatile (I usually just put frigate factories and trade stations on frontier worlds) whatever you want, your internal planets (adjacent to your capital) for techs, and everything in between just spam trade stations. You'll make a ton in no time, though you will definitely run out of money fast either way. What difficulty do you play on? AI gets super cheats at certain difficulties so you might want to get used to the game and its mechanics before trying anything harder than normal.
That is because Crisiss doesn't understand the difference between an experienced player and a new player.
Yes, SMAC stands for Super-MAC, which is the MAC station. The ability that prevents the planet from being conquered is, in my opnion, useless and money-consuming, as the first thing your enemy will try to bring down, after the SMAC stations, is your Anchor. So the ability won't be as useful as it seems, 99% of the time. You should invest more in other stuff.
That depends on many things, I have found myself multiple times having to rely on the black market to get a resource because of how the map got generated, e.g. I had no planets with titanium asteroids near my home planet, and had an abundance of Deuterium, so I had to constantly buy and sell resources on the market. Refineries are necessary to both races, and as Crisiss said, don't build more than one on each planet, but build more of them on different, adjacent planets. Balance the research of stuff with the building of ships.
SMACs are nothing new to the game or universe. They are featured in 2 of the most popular Halo games to date. There are also multiple audio cues he can listen to to get the idea. It's not even called a MAC station. I assume most people that play this mod are Halo nerds and know the difference. No need to be a dick.
