answer:I’m certainly no expert, but I imagine your best bet would be to buy an assortment and hold on to them for a while. By diversifying your portfolio, you’ll be ready for future changes: perhaps one character will come back in a later game and its value will increase. FWIW, I intended to submit a snarky answer, but then I realized that investing in something tangible for the long-term is probably a smarter idea than giving your money to investment banks to invest in magically creating more money. So good luck!
