This book is good for a Battletech fan. Ive been roleplaying in the Battletech universe on and off for years. The combat rules are balanced nicely. The reason I give it a 3 instead of a 4 is due to how unsupported the book is. There are no adventuring material to find online or anything other than lore. There is tons of lore. However, the lore is based on certain time periods rather than specific operations. You can buy books that show you famous battles and how to play them yourself using miniatures and some extra source books for battletech the turn based war game. Yet these do not provide roleplay opertunities. Although I can get pople to play time of war, they are always battletech fans who also roleplay with no newcomers. Perhaps as people warm to science fiction roleplay as they have been doing then there will be more need for a more fully fleshed RPG which could then feed back into the franchise. If playin with the wargame rules I suggest delving into the Chaos Campaign rules. This is great for a DM as it can structure where the next battle is coming from.
