Summons
By paying money on your smartphone in battle, you can summon help. A large number of characters can be summoned, including Gary Buster Holmes, Gonda Wara, a crayfish, and more. Summons can support you in battle through attack, recovery, and more.

Lots to take in here. One piece of great news is my man GBH is back, I assume his Japanese will be as terrible as ever. But... a Crayfish? Why? Hows it got a cell phone, and hows it attacking on land? lol I fucking love Yakuza. Oh, and apparently (Google search) Gonda Wara is diaper man from Kiwami 2. Easy asset reuse there!
Carting makes sense if they have a bigger city, but it'll hinge on control and course design, well Nagoshi did create F Zero GX and I enjoyed the Drone Racing, yeah this should hopefully be fun.
Now gimme the arcade details dammit. Oh, and Pachislot... gimme cheat items to make them fun. I love the detail in 5's but actually playing them for the completion list would have been a nightmare without the cheat items.
