TFU did have good technology but good technology does not necessarily make the game good. It was mediocre. Not bad, but mediocre. I had some fun playing it but both of them were very short games. I actually remember reading about the technology and being so blown away and thinking that it would mean that the game would be so fantastic. Pretty let down by it. The story was meh, but I don't hold that against it too much. For the most part the story works. I'm surprised you found it immersive, that's a first I've heard from anyone. But eh.
1313 was probably going to have all the bells and whistles visually of a AAA game. I just do not think it was likely to be as good as other games in the same genre. Given what we saw and know of gameplay it would have been somewhere in the area of Uncharted, Last of Us, and Tomb Raider. Uncharted is stupid amounts of good. Last of Us from what I hear is amazing. The newest Tomb Raider was great amounts of fun, and I just do not think 1313 would have been able to compete once you look beyond the nice shiney star wars coating. I was hoping it would be good. I wanted it to be. I was certainly hype for it. When I heard it was cancelled along with everything else I sat back and really thought about it and was like "nah, no reason to be upset. We do not even have a good idea of what it was going to be and LA's track record has not been great lately."
See like I look at your list and it suffers from some problems. X-wing is ancient. AMAZING games. Recently picked them up on steam and intend to buy a joy stick at some point in order to replay them. However, they're ancient. Battlefront is kind of a weird port of Battlefront games. It was fun and I know a lot of people who love it. But I think if you reskinned that as anything but star wars people would not care about it. I honestly dislike Republic Commando and found it just awful. I've been trying to replay it recently after buying it in a huge Star Wars bundle on steam and it is as bad as I remember. Just meh. Like it is not even as good as shooters during its time. The problem with a lot of Star Wars games is that they do not even stand up to games in the same genre. Like TFU is essentially a God of War style game. In every single way God of War is just better made. Republic Commando does have squad elements (which can be seen in games like Rainbow Six) but it is still a shooter that lived in a world where Halo was king. Now I do not even like Halo (the story blows) but Republic Commando was bad compared to that. Jedi Outcast is a borderline relic in terms of the kind of FPS it was. I might even say it was the last of a line, and Academy was a fairly mediocre sequel. Not bad. Like the only recent Star Wars game that was actually top of the line and a standout in its genre was KotOR which was not even produced by LA but licensed out. I think ultimately one of the big reasons it was good was because of the licensing. I also think TOR is pretty good if you think of it as a single player game which your friends can join you for.
None of this is to say that enjoying these games is bad. I've enjoyed my fair share of bad and mediocre games because I found them fun (which is one of the most important things about games). Same thing with music. I listen to some music that is just outstanding in terms of writing and composition, but I also listen to a lot of really crappy pop music. The latter is just crappy music. However, I still enjoy it, but I do not pretend it is good. Like the ability to enjoy something does not inherently mean that the product was good or of the highest quality. Taco Bell is terrible mexican food, but I'll still consume it when in a hurry and enjoy it. Like I enjoy playing many of these games because they are Star Wars and I love Star Wars and I want to consume Star Wars products. But my enjoyment of them does not make them good.
