I wasn't a youngster by any stretch of the imagination when I started playing the original Mount & Blade, and almost certainly put a couple thousand hours into it, with and without mods. Warband and a couple of mods for it have likely taken up another thousand or so. So far, Bannerlord has occupied me only for several minutes on a friend's computer, and I was extremely disappointed at how much the game LOST between WB and BL. In its current sorry state, I seen no reason to play it. To me, visuals are secondary, and won't fix bad design decisions or compensate for lack of content.
Just for the sake of comparison, I had previously sunk close to 5000 hours (most of it while unemployed for close to a year) into a heavily modded TES3: Morrowind, and making a few mods of my own for it. I wasted less than 100 hours on Oblivion before giving up on it, for some of the same reasons that I'm not happy with the direction TW is now heading. The things I disliked about OB were doubled down on in Skyrim, while several more things I liked about Morrowind were removed, or rendered irrelevant, so I never played Skyrim. I'm starting to suspect that if I do buy Bannerlord, it will be when it drops into the under $10 range, and major overhaul mods are available so I don't need to bother with the vanilla experience. Hope lives on, however, so I'm not giving up on the possibility that the developers may actually fix and finish the game (in another 8 years?).
Count me as "well into the 50+ range". My computer game experiences pre-date PC gaming by close to a decade, played on a mainframe and terminal in 1973.
