The weirdest thing ever in the franchise is DW6...
Ok, let's mention few glitches and surprises and even exploits in dw8/dw8xl:
1. Horse abilities being carried from ambition mode to story mode. Normally you can't equip a horse in a story mode prior to battle, however if the story character's default horse is of the same breed as the last equipped in ambition/free mode then all the abilities carry over.
2. 3xEnergy bodyguards allow for an infinite rage musou (until you're sick of holding circle or disconnect from the ground) when in red and with proper weapon for the characters with relatively slow moving rage musous. Won't work for say Chen Gong or Cao Ren because your bodyguards won't catch up with you but works beautifully with Xiahou Dun.
3. Allies utterly destroying Lu Bu at Hulao Gate on Ultimate. Seriously...they rip him apart. I can't even do anything because Sun Jian and co just go berserk. I've played the stage dozens of time and they always destroy him. Never seen Lu Bu defeating any of my allies there.
4. Another bodyguard exploit that ends up badly. Try stacking ambushes one on top the other. The AI backs off...sometimes off the map. You can't get him so all you can do is hope that the panic status expires before your allocated time. The most embarrassing defeat ever.
5. Generic bodyguards stealing your kills. I swear they do it intentionally

many times I'd see them blocking and waiting till I reduce the AI health and then they land a killing blow.
6. Cao Cao's freezing musou freezing my game

PS3 is handling the game nearly perfectly and I had only 3 crashes in countless hours. All 3 happened after I activated double musou with Cao Cao. Pretty cold, cousin...
Do what you believe is right and don't be distracted by praises or insults.
