A much more general thing but, just in principle, a game where characters can start off as capable, experienced individuals. Virtually all games seem to love making starting characters essentially useless before they then rapidly grow in power over the next X number of months, or perhaps indefinitely forever. That growth can be in stats, equipment, etc and I hate it when it works like that.
Quite often the only way to convincingly make a character who is say a capable 40 year old to be taken seriously is if you do it immediately after the game launches. One of the things I did like about some of the old Fading Suns games is that if you came out of character generation with a goal of 16 in something? You were about as good as anyone got with that skill, maybe there might be somebody around with a 17 but only if it was a popular skillset.
Older characters would absolutely round out their abilities, get higher stats, etc, but that only went so far. I had a fresh out of character generation person challenge my character to a duel on Vargo and you know what? It was a pretty close duel despite my character having been one of the most active in the game for almost four years and being combat focused. She got disarmed at one point and only won because this was a known risk in duels and so I had her carry huge knives as backup weapons following prior experiences.
Given that their character was also combat focused and had presumably not sprung out of the ether the moment they started being active in the area of the universe covered by the game? That was fine and good.
