Despite that little has changed since Dynasty Warriors in 2000 on PS2, this series is still fun to me.
Like a space shooter, it's all about not getting hit and killing as much as you can.
The constant flow of more character and upgrade options makes it better with each new entry, too.
I can undertsand why people don't like it based on its repetition throughout the series, but that usually just means they never liked it in the first place anyway.
I also tried the Gundam one and it was pretty cool.
