Firstly, I find myself wondering how somebody gets to be flying an Anaconda without naturally playing the game long enough to unlock engineers and collect a sizeable supply of mat's.
Beyond that, I understand how G5-engineering a big ship, with a heap of weapons and modules, can seem a bit overwhelming but it's a lot easier if you moderate your goals and it doesn't
have be a grind.
For example, here's my multirole Annie build:
https://s.orbis.zone/bs8L
Now, let's dial that all back to G3 engineering:
https://s.orbis.zone/bs8R
It's a bit slower, has a 5ly shorter jump-range, uses a couple of MW more power, has slightly less shields and loses a whopping 9 DPS.
For comparison, here's the same ship without any engineering:
https://s.orbis.zone/aqu_
All in all, the G3 engineering is a BIG improvement over non-engineered but not
that much worse than G5.
So, let's take a look at what mat's it'll require...
Carbon: 12
Chromium: 12
Germanium: 5
Manganese: 25
Nickel: 18
Niobium: 9
Phosphorus: 26
Selenium: 6
Sulphur: 22
All these raw mat's can be obtained by taking a trip to the shard sites, collecting a heap of G5 mat's and scooting back to a mat' trader in the bubble to swap them for what you need.
A nice little mini-exploration trip. Hardly a "grind".
Chemical Distillery: 3
Chemical Processors: 7
Conductive Ceramics: 15
Conductive Components: 35
Electrochemical Arrays: 9
Focus Crystals: 15
Grid Resistors: 6
Heat Conduction Wiring: 5
Heat Dispersion Plate: 6
Heat Exchangers: 9
High Density Composites: 6
Hybrid Capacitors: 15
Mechanical Components: 3
Mechanical Equipment: 2
Salvaged Alloys: 25
Shield Emitters: 10
The vast majority of these Manufactured mat's can be obtained through combat which, conveniently, is currently very well paid.
Go find a system in Civil Unrest, with Pirate Activity POI's and get your pew-pew on for a couple of hours, in a ship with some collectors, and then stop off at a local station to earn a few million credits for your trouble.
Alternatiely, find a tourist beacon in an Anarchy system and explode some Belugas.
Or, take on some (very well paid) Massacre missions and hoover up the mat's.
Or go visit Dav's Hope or any of the other sites where mat's can be collected.
And then, once again, haul your swag to a mat' trader to swap some of the high-tier mat's you'll have for more low-tier mat's.
Kind of repetitive gameplay but only as repetitive as "playing the game", in general, is.
Atypical Disrupted Wake Echoes: 3
Distorted Shield Cycle Recordings: 21
Exceptional Scrambled Emission Data: 9
Modified Consumer Firmware: 13
Specialised Legacy Firmware: 9
Strange Wake Solutions: 3
If you've been scanning ships (you
have been scanning ships, right?) as you play, chances are that you already have most of this Encoded material.
Failing that, go visit the Jameson crash site, collect G5 scans and then hit up a mat' trader to get what you need.
Alternatively, take some missions that pay in G5 Encoded mat's and then trade.
Or visit some of the surface installations that yield G5 Encoded mat's.
Or visit some Encoded POI's in space.
Again, not the best of gameplay but hardly a "grind" and there's plenty of different activities to choose.
So, all in all, the mat's required to build a G3 Annie can all be found by doing the same things you do while playing ED normally
or by going on little adventures which
should actually be enjoyable to somebody playing a game that offers access to an entire galaxy as a sandbox.
Course, there's unlocking the engineers too, but those are one-time events which a player
should really consider as challenges and enjoyable alternatives to regular gameplay.
Honestly, it sounds like the OP is just salty cos he isn't getting immediate gratification, rather than because there's any real hardship or grind involved in obtaining the required items.
