Just curious about this, what makes Mario & Luigi titles to feel different compared to i.e Killzone Liberation? Both games takes a very different approach (from platform to RPG, and from FPS to tactical person shooter), but both games are set in the same universe (Mario and Killzone universe respectively). What makes one game feel like top tier while the other feels like spinoff? I'm not thinking about how fun the games are, but more about in an objective view.
This is a really good question test_account, and its tough to explain as its more of a feeling related thing.
But I will try, from my perspective. I understand not everyone may share the same opinion which is fine.
First off, I did enjoy Liberation during the short time I owned it, but it never really held my interests. I much rather Sony published a game like Liberation rather than try to squeeze an FPS Killzone onto the PSP (even if such a hypothetical shooter was a spinoff of the first game) and have a fresh take on the franchise.
But herein lies the issue: Liberation is based in the Killzone universe, one primarily that is known for being a First Person Shooter.
While you bring up the fact that Mario & Luigi was set in the same universe and was of a different genre, it was a completely different experience with a completely different take on the franchise as a whole. I would suggest that Mario games seem to have their own "genres" and even though we see Mario pop up often, the games that are not centred on Minigames are often of top quality.
Mario & Luigi itself could be seen as a separate franchise from other Mario games the same way Kart could be seen. They are chalk full of humour, little innocuous hints and throwbacks, exploding with charm, and play completely differently from both a story stand point and an thus as and overall experience. It is almost in essence a completely different title and doesn't feel like a spinoff in any way, shape, or form.
Killzone Liberation on the other hand, feels very much so like a companion piece to the more important console brethren. When I owned a PS3, Killzone 2 was the game that interested me and I took to as the main piece. I enjoyed that game quite a bit, whereas the PSP version I picked up out of enjoyment for the franchise in general but it could never hold my attention because I wasn't as vested in the franchise and more-so it felt like the real action was meant to be on the console game.
Mario & Luigi isn't on any Nintendo home console.
To better illustrate what I'm confusingly trying to say, let me show you what I'm trying to mean:
Killzone games released for PS3 & PSP:
- Killzone 2, Killzone 3 (PS3)
- Killzone Liberation (PSP)
Ultimately, its the same franchise, same setting, same everything minus the presentation of the games (FPS vs tactical shooter) and thus the overall feeling is more like a companion piece rather than a full on engrossing adventure.
For "Mario Universe" games on the Wii & DS:
- Super Mario 64 DS (DS remake)/ Super Mario Galaxy 1&2 (Wii)
- Mario Kart DS, Mario Kart Wii
- Mario & Luigi 2, Mario & Luigi 3
- Yoshi Touch & Go*, Yoshi Island DS*, Super Princess Peach*
- New Super Mario Bros. DS, New Super Mario Bros Wii
- Mario Hoops 3v3 (DS), Mario Strikers Charged (Wii), Mario Sluggers (Wii), Mario Tennis (Wii remake), Mario Sports Mix Wii,
- Mario vs Donkey Kong (DS)*
- Super Paper Mario (Wii)
- Mario Party 8 (Wii), Mario Party DS *
- Mario & Sonic @ Olympics (all 3 of 'em; both on DS & Wii) *
- Dr Mario* (DSiWare)
This is excluding the 3DS games of course, and yes there are a lot of Mario games
But consider how I grouped the games. Sure, the *'s represent more far reaching games. But to me they also represent titles that could qualify as spin offs.
Everything else is a different franchise; Mario Kart; 2D Marios; 3D Marios, Mario RPG's might play similar to the Paper Mario series, but are entirely different in many ways; Sports games, Party games; the point is these are completely different experiences for the most part.
I hope that answers your question somewhat.
