So the standard Cappella Uber Alles BS and nothing resembling a win. Check.
The TRO is published in 3145 when the Davion's are losing ground. So nothing has changed since the year hasn't changed. There are one or two captured units used effectively by the other factions. But for the most part, the TRO presents a collection of absolutely beautiful (That Zibler Hover Sports Car-Tank is amazing) vehicles and mechs. All of which have really interesting stats.
Its a great buy for any FedSuns player wanted to see the awesome new units they've got. Or for any DC or CC player to blow up or (Hopefully!) capture some awesome equipment.
If you are a Federated Suns player and want to know how the Suns are fighting tooth and nail against their would be conquerers its a wonderful purchase.
If you are a Federated Suns player with an axe to grind its worth buying so that you will have absolutely awesome mechs, vehicles and Fighters (Those fighters are gorgeous) on the field for when you flip the table.
Anyone from those three factions should take the plunge. :D Or anyone else as well! Looking forward to driving Vulpes around.
Edit: I think you'll find what you want to see in the TRO Crunch. :) But I hope that you start wanting to find something else from Battletech soon.
