My reputation started slowly to build up and I could purchase my first combat ship - Starburst. This also hepled alot as I stumbled accros multiple abandonedn M5's wich I could sell easily for 1M a piece (including equipments installed). Simultaneously I used my M5's to expand the known universe with advanced satellites. Put all purchased TS to Sector traders and finally to Universe traders. Buy all used ships below 80% hull, repair them and sell. I started with quite similar gameplay as most have recommended.
I chose to install also satellite network mod to get more data about sectors in which I have satellites - to find all those goodies :) It exceeded all my expectations even on the basis from Willfe's videos and multiple forum threads.
So I installed it, started playing with the start containing TS + 3 M5's, and was quickly sucked in to the amazing depths of work Litcube had made. Slower paced and more tactical combat, SCH, dockware managers, missile defense 'on user request', the new enemies. Wiki and all other available information seemed even too good to be real. After that, it got easily quite dull as you knew that you win the combat if you play correctly. There was always the ships with 'I win' embedded in them and acquiring of those ships were always the main goal. While having played multiple runs on vanilla X3AP, both without and with some mods, I started to find it a bit boring.
