My personal opinion on Tau Ceti so far
Pros
-Lots of new stuff, new ships look good, new blasters, rockets sniper blasters look decent. However sniper blasters would have looked better if they have had these wires that connect on the front sides of the ship like the other systems.
-New units look really good, really good job with the completely new ancient designs for the ships in Calon especially the Ra.
-New components are by far the most we have seen in a new system, considering tau ceti's amount of new componets fits exactly 2 classes that's the most we have ever seen.
-Most interesting part of the story to look at, story so far is well done and always intrigued to think of what part 4 or even onward would reveal.
Cons
-Difficulty is the sad part of it, not every game is supposed to be easy and i can understand it shows that the more you progress the more skill you'll need and the harder it gets but tau ceti is a big jump from draconis. I remember in one of your posts you have all intended to make it just as hard as draconis if not slightly harder. But tau ceti is exponentially harder, many of us believe it is half based on sirius as some of the enemies have much more HP since it takes much more shots to take them down on our own than it would in a lower system. For example, if i were to fly a gemini ship and go to gemini and fight a ds solo, i can handle it, but if i were to go in tau ceti in my tau ceti ship, in less than 10 seconds i would get completely obliterated and stand no chance unless i'm in a really armored ship and be extremely careful. You have either made our ships relatively squishy compared to other systems or the damage the enemies inflict is crazy, this part might just be me but i have a clear notice if we aren't careful, our ships get destroyed quickly but it's not like that in lower systems. Even running into a ds then just getting away can be troublesome, a second they see you the next time you look at your health you're at 30%
-The worst part is that your tau ceti level ship is slow and what i mean slow i mean slower than the enemies by a bit. Earth in unrest by far is the most difficult planet to travel on for example, ancient baiters catch up to me easily even if i have my afterbruner on and traps me then game over. And by the way i have my speed drone on. Many people as a result of that are forced to buy engine boosters to have the chance to escape enemies etc.
-Enemies and new tech don't have any descriptions except for the ships, this is the only thing i can say that makes the system look in a way unfinished, i.e. the new mantis units in venar have no description whereas the current mantis units we have currently seen have descriptions, the pirates/raiders don't have descriptions either. It would be nice now that we have observed the ancient units more from sirius they could at least have descriptions in tau ceti. What makes it more unfinished is the description of the tech, absolutely nothing, it would be interesting but the way it says "no information about this item or doesn't exist in intergalactic database" makes it look more like an error in the coding. Especially for sirus. Another problem relating to that is the names of the tech, this is ever since sirius started, for tau ceti i was expecting the first blaster to be called "neon blaster" and perceptron blaster to be called "neon power" or "neon enhanced". Either way every single component sound the same and it kind of makes it dull in a way. It would by nice if we give them names by their technology with descriptions. I might even make ideas on what to call each tech.
-The cons i have mentioned do not outweigh the pros at all, but the reason i spoke a lot about them is because i personally think they're important to have a look at. I already know that the enemies hp were reduced by a third so it might just be me. about the difficulty and i think descriptions would make it much more interesting.
