GameSpy writes: "It seems strange that the Wii has been out for nearly a year and a half now, and a traditional RPG hasn't been released for the system (Virtual Console aside). That's about to change now, thanks to Koei and the oddly-titled Opoona. Developed by Arte Piazza, Opoona features the input of Dragon Quest veterans Shintaro Majima and Sachiko Sugiura. The game's soundtrack is composed by Hitoshi Sakimoto, who previously did the music for Final Fantasy XII. The game has an impressive pedigree, but can it live up to its creators' previous efforts?
The main character is the titular Opoona, a member of the diminutive Tizian race. He may look like a noseless version of the cartoon character Ziggy, but we won't hold that against him. Opoona, his parents, and his brother and sister are en route to the planet Landroll for a vacation when their spaceship crash lands on the surface. Before the crash, the adult Tizians were able to get their children into escape pods, but now Opoona is separated from his siblings and his critically injured parents."
Pros:
-Unique and fun combat system
-Great design and music
-It's challenging
Cons:
-Bureaucratic backtracking is a pain
-Static camera during dungeons
-Domes can be tough to navigate

Phil at SPC writes, "Welcome to the return of One & Done, an article series on SPC that talks about games that never became franchises. They were literally one and done! Now, the purpose of these articles isn't to beg for sequels, as some of these games don't need them and not every game needs to become a franchise. Instead, we're just exploring and fondly remembering these terrific titles from generations' past and giving them some more time in the old spotlight."
I also remember Cold Fear. Never wound up buying it but I watched some of the walkthrough years later.
Gun could’ve gone on, but RDR was a tough act to follow.
Early years of the following gen had quite a few one-shots. Heavenly Sword, Lair, Haze, Folklore, Stranglehold. Bah gawd Stranglehold had expensive DLC for its day.

Nintendo's motion-controlled console was the home of countless fantastic gaming experiences. Here, I'll count down ten obvious and obscure choices that will suit the modern market perfectly.
This console has so many great games. I'd like to see a sequel to The Last Story.
There's not going to be a sequel to the structure of Super Mario Galaxy 2 though. The only reason we even got SMG2 was because they had plenty of leftover ideas from SMG1 that didn't make it into the game. It's better that we got other structures of 3D Mario later on
Super Mario Galaxy is getting a sequel though...Odyssey
Super Mario Galaxy 2 was a one off mainly because they apparently had content left over and instead of it wasting they made another game since they were still in the consoles life. Wouldn't make sense to have a sequel to Galaxy when each new system has brought us a different, brand new main Mario game. I'm glad we got Odyssey over it, it looks great and more open then Galaxy. Once you got to certain point in some levels of Galaxy (star cannon) you couldn't go back so back tracking was limited
Missing a lot of games: Red Steel, Zack and Wiki, Little King's Story, Bloom Blox, De Blob, Muramasa, Excitebots/bikes/trucks, Sin and Punishment, Kloana, Battalion Wars, etc . . .
Super Mario Galaxy 2 doesn't need a sequel. You could see the ideas drying up when playing through it.
