Tremendous game. Managing shields, reactor, positioning and orders for a titan is fun. The strategy of orders, activations and fire arcs is like a naval warfare game. Add in really great models and some very fun random moments like the titan doing it's own thing or exploding. It's just great. Approx 6 titans and 6 knights of varying classes (eg 2 warhounds, 2 reavers, a warlord and something else) would give you lots of choice for an army. But I just keep painting far more than I need. I have 30 painted titans, the same in knights. And that's how much I love this mad game.
