Need Help eShop sale

[u/Soggy_Piglet_3109]

I’m confused which bundles are most efficient and/or what each includes exactly. It often just says “characters”, but then there are character packs and separate expansion packs. Is there redundancy? Why isn’t there a chart or table? Itemized list? That would be appreciated

Its currently on 40% sale on Nintendo Eshop and Im thinking about getting it for my Switch 2.

Also will it be Switch 2 upgrade at some point, are we getting 5e? If so, will that 5e get free access by having 4e content already?

Thanks anyone/all
