As did most who bought this game TRoS brought me to it. I come from playing one of the most universally hated RPG's ever, Rolemaster. I've played countless RPG's over a forty year time span but my favorite games have been Rolemaster, TRoS and now BotIT. I like crunch, I like simulationist combat. I don't like telling the GM/DM/KEEPER/WHATEVER I attack. I hate those words! I want to explain exactely how I attack or defend. I want the ability to kill someone when I sneak up behind them with a dagger in one shot just like how you would do it in the real world, not do seven hit points of damage, have him turn around and continue fighting me at full strength, ridiculous. Combat in TRoS and BotIT give you that power. For me every RPG can be summed up in how it resolves combat. Yes, I'm a minority report. If you want awesome combat on a level that no other game can give that's why you buy BotIT.

If you want pretty much anything else you are in the wrong wheelhouse. This game is about brutal, simulationist combat that surprisingly runs very fast. In a typical D&D 5.0 session a fight against some Kobolds could last a five man party one or more hours in BotIT it could be over in a minute or two, fifteen minutes is about average. This shows that simulationist combat does not always mean long and tedious battles.

How it improves, in my opinion, on TRoS:

Limelights: This mechanic allows players to fight until a significant event occurs to them or their foe then shifts the "limelight" to another player, brilliant.

Use of d12's: TRoS used d10's, it's an improvement to add the additional scale of d12's, not huge, but an improvement.

Combat: The combat moves are better defined and laid out in most cases. The improvements are sometimes subtle but they are there.

Spell System: I prefer the darker themed spells of BotIT, however, this part of the system is under developed and could use a book on magic.

Passions: A better mechanic to the similar mechanic in TRoS, not a massive improvement but better.

Most of the improvements to TRoS are small and incremental. The designers of this game clearly liked TRoS and followed it closely in many ways. TRoS does have an advantage in that sourcebooks followed the rule book so you have much more material to use. Good luck grabbing the books for TRoS but the PDF's are floating around to be had.

Not an in depth review just a touch on those aspects that I enjoyed the most. My only wish is that the creators of BotIT would crank out source books but alas I think my wish is going nowhere on that.
