Didn't star fox adventures sell well?
Not as much as 64 or SNES but it did good considerin how the Gamecube was at the time. (And it sold over a million copies which for me is good enough considerin that it is Nintendo)
If you think about it, Star Fox has a much better attach rate than Metroid *gasp* (If you compare the numbers to the number of systems sold, you get this)
6.09% of SNES owners bought SF1.
12.24% of N64 owners bought SF64.
8.6% of GCN owners bought SFAd.
4.97% of GCN owners bought SFAs.
0.34% of DS owners bought SFC
1.78% if 3DS owners bought physical copies of SF643D.
Metroid: 4.41%
Metroid 2: 1.48%
Super Metroid: 2.89%
Prime 1: 12.97%
Fusion: 2.06%
Prime 2: 6.12%
Prime Hunters: 0.48%
Prime 3: 1.75%
Other M: 1.25%
If you look at other series attach rates such as Zelda, Star Fox is not doing too bad (Considerin that the budget is lower & it usually does not get the attention that Mario & Zelda games get) & those that think "Oh its doomed to suck forever, it don't sell well!" should chill out. IMO, there is no decline, it still reaches 1 million units sold (Which for some reason isn't good enough to people) & the attach rate is moderate. The only thing I'd comment on is Command & it wasn't because it was a terrible game (Although I'm not a fan of it), no, it was because it came in the era of "Touching is good" DS, it came out in the time when DS units were not selling good. Command was just a victim of timing...perhaps if they waited a bit more, it would help but that was then, this is now.
Also adventures was highly praised, just not something for people to expect it playing like the original star fox games.
Yep, thats most of the positive reviews in a nutshell.
But its not like mario stuck to side scrolling, series innovating is a wonderful thing and these unimaginative origin loyalists can **** off.
And it isn't like Zelda stuck to being an RPG Adventure, Zelda II: Adventure of Link has influenced the franchise & I find it laughable that people think its the worst Zelda game made (Not counting CDI)
