Might have to check this out. I haven't read this whole thread but how long does a typical run take?
Depends on how familiar with the game, but usually 25 to 30hours isn't uncommon if you're not playing really fast. I think people who play fast get it down to like 6-10hours or so but personally my fastest runs were still around like 18hours I think, I like to take my time to consider the options and stuff.
I didn't know there was a thread for this, I played a lot(1k+ hours) of ToME a few years back, cleared the game on every class(and there's a lot), it's a great game if you're into traditional roguelikes and especially the combat aspect(since there's not much else), very deep char building and lots of variety in classes and races.
It does take a long time for every run though so it doesn't lend itself to "true" roguelike instant death and why it defaults to adventurer mode(starts with like 1 or 2 lives and get more as you level up, up to 5? 7? forgot it's been a while). Balance is also kinda all over the place, some classes are much stronger than others, and some mechanics break lategame pretty hard if you use them(the crafting thing in lategame with one of the DLCs for example makes even the shittiest class able to bulldoze the endgame).
Another issue is the game is currently in limbo, with the main dev having issues since Covid, so while a new DLC was announced a while back, it hasn't been released yet. A year or so ago there was some news of a beta being "soon" and that also hasn't happened yet. The game is perfectly playable as is but unlike many other traditional roguelikes it's not getting frequent updates. I think last update is like 2years ago or something?
The game is free though(you can download the free version on the site), have to pay for DLCs and they're quite nice but if you're curious grab the free version and just play. Steam only has a paid version, the money gets you a bunch of cosmetics and the Possessor class(which is a buggy mess, but a fun one, it's more an advanced class though since you kinda need to know what every skill and mobs do to get an idea of what to possess). You can just transfer the saves if you end up buying it on steam after.
