Ok, now you are just intentionally missing my point. If I put my dick in you, it doesn't mean that you become me. You're still you, with a bit of Haba dribbling from your hole.
So what's the difference between Baldur's Gate and JA2?
Jagged Alliance began in 1991 under the name of "ambush" as a real time strategy game where you manage a team of mercenaries.
Bioware doctors were PnP RPG geeks and they wanted to try their hand in making a PC cRPG, so they made Battleground: Infinity - a real-time multi-player RPG. They got AD&D license after demoing it to a publisher, and thus Battleground: Infinity turned into what became Baldur's Gate.
Jagged Alliance characters have hidden fixed traits and they have stats.
Bioware's characters have hidden traits, stats and extensive backstory and personal quests.
Jagged Alliance was built from the beginning to be a tactical war game with a strong strategic layer. The "characters" have personality, but you can't influence it. Their stats improve, but they do not evolve throughout the story. JA mercs are tools, to make them more interesting and memorable they have personality. They could be tanks or robots, the
game wouldn't change that much.
BG was built to be a computer RPG that'd appeal to a wider modern audience while being faithful to the AD&D rule-set and the Faerûn setting. NPC traits and personality was added for storytelling reasons, to make the game more immerse.
Jagged Alliance got more RPG-like features through the development (though many of those have been solid part of wargames for decades). Even though more icing was added to the cake, the core of the game remains the same. It is a strategy game with a tactical, turn based layer. You kill enemy chess pieces with your own pieces and try to win the scenario.
If you start removing similar RPG features from both BG and JA, in the end you'll have a role playing game and a tactical strategy game - because that is what those games were designed to be. RPG-like features do not make a war game RPG, they will remain as superficial flavour additions.
