X:BTF would be too long to do because of only possible way to earn money is by trading from factory to factory.
X-Tension has no storyline to go though.
X2:TT - Is a game I could be able to record, and might be shorter than X3 Reunion and I just reinstalled X2.
X3:Reunion - I haven't finished it! But it has the secret unoccupied ships laying in sectors.
X3:TC - I haven't played.
(This is a X2 Speedrun Topic. If somebody is willing to try to run X:BTF or X3 then please make another topic so we wouldn't have conflicts on which X we are talking about)
But I wanted to talk about speedrunning X2 - The Threat.
So here is a short overview of the main goals:
1) Start with Easy Difficulty(It just would have a longer start if it was played on X-TREME)
2) Go-To Home Of Light headquarters.. take mission
3) Go-To Crystal Fab in Ore Belt and sell components.
4) Go-Back to HQ Take second mission and fly the Express to Atreus' Clouds Trading Station. Talk to Saya Kho.
5) Go-Back to HQ ignoring the pirates(in SETA the pirates shoot more rarely and hit rarely).. talk to Elena Kho
6) Go-To Ban Danna in Argon Prime.
7) Go-To Goner Temple. Take mission with Bret. (I haven't tried going without him)

9) Go-To Antigone Memorial Sector in the Middle
10) Go-To HQ.
11) Go-To Priest Rings. Kill some pirates and then go into trading station. Talk to Manckossak pay 33'333 credits
12) Go-With Saya on the unsafe route to Nyana's Hideout. Do the mission sequences there.
13) Go-To Black Hole Sun and wait for Ban Danna's message.
14) Go-To Ban Danna at Argon Prime
15) Go-To Ore Belt. Do the mission sequences
16) Go-To Ban Danna at Argon Prime
17) Go-To Rolk's Drift and pay 150'000 credits and Jump to Khaak Sector
18) Take The Box at Unknown Sector and Jump back to Rolk''s Drift.
19) Go-To Omicron Lyrae. Do mission sequence there.
20) Go-To Ban Danna at Argon Prime for the last time... DONE!
Now how should this go through in a speedrun?
1. before step 2) fly the discoverer to Atreus Clouds and then go to the HQ. This is for Jumping the express reasons.
2. at step 4) buy a jump drive which can be afforded if one 25MW shield is sold, buy a total of 100 energy cells and full engine tuning from the HQ(- 101'000 - 1600 - 10'00 ). Jump to Atreus Clouds, Auto-dock at the trading station and talk to Saya. Then with Step 5) jump back to Home Of Light and Auto-Dock at HQ, but with all the pirates around auto-pilot cannot dock at it so when very close to the HQ the express needs to be docked manually. The Pirates don't do a lot of damage while in SETA(might be a game bug) cause of rare fire rate and hit rate of the pirates. Before finishing step 5) sell the other 25MW shield and the weapon.
3. Between steps 6) and 7) buy 20 or less mosquito or wasp missiles for the squash mines mines at

4. The steps 6), 7),

5. For now let's say I have a Buster after step 9). Though it might not be the best ship to fight against Pirates in Step 11. It might work if it is placed before the docking bridge when exiting the Pirate Base, and start shooting the base till the guards come out and then shoot them in the back until you have enough reputation to dock for Step 11.
6. For now I don't remember how it was with the "Follow Saya To Nyana's Hideout" mission and how many hostiles there might be. But im worried that a Buster won't be enough to take out the Khaak in Nyana's Hideout so we need to get back on step 4) to earn the 1.9 mil for the Nova. With a fully equipped nova that has a jump drive all the further missions are possible.
Hints and suggestions are welcome!
