Behind the navi idea was nice, if you bothered to do the quests, you would find out that those navis play a big roll in what you need to do.Star Force's behind-the-navi idea is OK, but I felt it took a lot away from tactical play. You don't plan nearly as much, the entire battle consists oo of dodge, run up and attack, dodge, run up and attack.
Star Force had way too many low-points it to be a good game. Maybe it's because I didn't play longer then half-an-hour, but that's just because the game bored me quite easily.
Battle Network series did the same as well, except it made you steal area and dodge, run up and attack instead of being able to lock on.
That could be it >.>
Frankly, I found the series to be a great new addition to the Rockman library, cool bosses, and the 3D made planning much harder because you only have three spaces to work with, and if you don't do a lock on attack fast enough, you'll get hit if the enemy walks in front of you.
Plus if you unlock the final bosses GX/SP(Can't remember) form, it will be a run for your money, because in Ryuusei 1, Andromeda SP/GX(Whatever) was insane, and I had the best record time for all my Navis and all the chips including a lot of great combos.
The game is great if you give it a chance. Plus you get to see Megaman if you used a Battle Network game 200 years in the future!
Lan comes back for a brief Cameo or something!
