For me, the most frustrating part of the
Dynasty Warriors series is the lack of strategic elements. While I would love higher order strategy in the vein of
Kingdom Under Fire: The Crusaders, I would be more than happy with a few troop commands. It doesn't have to be a complicated overhead HUD; just a simple "Push (Up) = Follow Me" would be a major addition.
Dynasty Warriors Gundam 3 attempts to layer in some strategy by adding key areas to the battlefield. Capturing certain areas of the map yields advantages, like launchers or the ability to call in a partner. The idea is great, though it is hard to see it as anything other than a distraction from bigger issues. Look at this hand, not that one. It is hard to build any sort of workable, strategic battle plan. Allies make own way through each mission with little regard toward capturing key points. The encounters usually end badly, putting you at a major disadvantage since everyone shares the same deployment points. I hate having failure forced on me because I can't bring some order to my army.
Your sole motivation throughout the seemingly endless parade of same song missions is the prospect of unlocking your favorite pilot from a particular series, or finding a better version of your mobile suit. During missions, you'll find plans for new mobile suits. Even identical suits can have different stats, adding a slight bit of Diablo-style loot whore madness. Building plans unlocks new enhancements, which can increase certain parameters for your suit.
The system is a nice touch, but too much is assumed. The menu system is terrible and full of unnecessary redundancies. There's no way to tell which Gundams you've built stumbling through multiple menus. As a player who loves this sort of play element, I rarely touched it due to the associated frustrations. You're also able to assign "Operators" for each mission, though I was never able to figure out what they did other than fill the battle with more chatter.
To its credit, Gundam 3 is a refinement over other games in the series, though the refinements fail to address the series' bigger issues. It is the equivalent of putting racing stripes on a rundown, rusty station wagon. Fans of either Gundam or Dynasty Warriors probably won't notice issues, but everyone else will.
It is hard to recommend Dynasty Warriors Gundam 3 as anything other than a guilty pleasure. It is not a great game by any means, though every once in a while, the thrill of carving through enemies overcomes the game's noticeable flaws. Unless you are a fan of either series, consider Dynasty Warriors Gundam 3 a gamble.
