I think there was just so many things that we could do right form start in X3 games.... Here in XR we are limited. Whole point here is just to build stations and trade(that is point of all X games but there was more to them than XR have right now) . And even that is limited with AI that is too stupid do simple tasks. And almost no control over our ships and stations... And there is limited sink too so sometime there is no point building stations in some sectors.....
I think what made me start replaying X3 wore:
Reputation system that was more realistic than what we have right now. It was more fun and we had to work for it. We cant buy better weapons or ships if we don't have enough rep for them.
Able to pilot different ships. We had ability to pilot almost every ship in game and it was challenge to actually get one (especially capital). In XR this is way too easy. But on the other side it is huge challenge to try control and tell AI to do something
More station trading and freedom. I think best sell and buy opinion wore best thing EGO made. Also ability to tell ships what job they should do. Now everything is run by idiotic AI that cant do anything right
Barter System. Man I loved that thing in X3 games. If I couldn't find weapons there is always chance ill get them there (especially capital weapons).
Map was much better and we had more options for our ships. Like shot down missiles or fly to that location or defend this location. And even thou it was horrible they had fleet formation. Now I tell my ships to attack and only main ship is attacking and rest of them are just standing and watching
Also number of weapons and missiles we could put in cargo. Whole cargo system was fund and we had to make choice between them.
That was some of things that always brought me back and reasons why I had fun restarting game. There was always something different I could have done and different ship I could have piloted. But XR is not that horrible too.
I like how we build stations and how they need materials to actually build. All thou I wish we could tell Architect to just build whole damn station at once.
I like how new mining system woks... It brings life to economy.
Visual production on stations and shipyards actually build ships by using materials... This is something X3 games wore always missing.
Station interiors and cap ship docking. I think this is good idea but it is too bad there is nothing to do there. Also they should build cap ship bridges to.
I like new cap ship battles and how we can damage their modules. Also boarding is pretty fun too. In X3 boarding sucked LOL
There are a lot of good things in XR but there is not much to do just like in X3 games. And it gets boring just build stations after some time. Specially when it turns out that they are useless because they don't have sing and we don't have galaxy trader. In X3 we could just jump to pirate sector with our fleet and destroy everything just for hell of it(if I get bored). In XR we can do same thing but we need to fly tough million jump beacon and gates to get there and half of fleet will be lost do to bad AI

Also we cant destroy stations in XR

It's not world hunger because we can't feed poor,it's because there will never be enough to feed the rich .....
