Adding a basic single player world isn't enough, especially when it comes at the expense of evolving the world championship options. Depending on what you are buying it for, 5D's can be worthwhile. However, if you looking for an excellent single player experience based off the card game, you'd best skip this one out.
Trendy Gamers: After the complete disaster that was the XBLA Yu-Gi-Oh! game, my faith in the series had almost all disappeared. So, when I saw this game at the pawn shop, it took me some convincing to pick it up but luckily, it restored some faith I had lost.

Stardust Accelerator is passable only when you look at what makes Yu-Gi-Oh! so popular. Konami only had to incorporate the cards and the rules (that have been in place for how many years now?) and they would've been golden. Everything else is below par and not worth your money.
