No. It's just in general considered one of the best launch lineups as a general rule.
So let me get this straight. The lineup didn't got great reviews, didn't sell good and didn't push the sales of the console but it is one of the best ever? Based on what metrics for you to say it is a general consensus?
I never said the games didn't get good reviews. You bet your ass Power Stone, Soul Calibur,Sonic Adventure,Ready 2 Rumbe,Hydro Thunder,House of the Dead 2,SEGA Rally 2 got favorable reviews. Dynamite Cop was a super fun arcade beat em up. I play it at least a couple times a year. What game isn't awesome using loss of clothes as a health bar and the option to beat up enemies with bread or meat then fight a giant octopus? Still an entire cult around Power Stone still claiming it's better than Smash. I like PS a lot but I won't claim that. Personally I also found Expendable a fun top down shooter. Soul Calibur looked miles better than the Arcade version and it's the game that got the series as popular as it is. Still a great game. Sonic Advenure upon release reviewed well. Just in the years since has it's flaws been more apparent.
Console failed due to SEGA being bankrupt from Saturn. DC also could not play DVDs and that was a huge factor in PS2 early success.
DC actually broke some launch day records for the time and did well it's first few months in the US but SEGA's money problems combined with they messed up the launch in Japan and Sony hyping PS2. DC could not play DVDs and no EA support (for using PowerVR2 instead of Voodoo2 which had a faster fillrate and the Glide API was popular at the time) They did not go with Voodoo2 due to 3DFX breaching contract.Great console but circumstances did it in. Not it's library as the system had a great library and still getting games. I plan to get Xenocider soon. Maybe even Joshprod racing. Circumstances killed the system. Not it's library.
I been using forums (most non SEGA but retro forums) for 25 years many forums (their main site with articles) and a lot of times DC comes up as one of the better console launch line ups. This is only a sample but it often pops up in websites when they rank top console launches. This is not cherry-picked, This is just from google when searching for the best console launch lineups first page. This is only example list not an end all list.
This is just a general search and the results on the first page. I have seen it pop up in more lists over the years. Some sites no longer with us and others just in general. Launch lineups never really determine a consoles success. Saturn had a good one but bad architecture and marketing did it in. Sony systems generally don't have great launch lineups but they sell well as over time they get most the best stuff. Gamecube and Xbox have better launch games than PS2 but PS2 was the better system in the long run. Xbox One probably had a beter one than PS4. At least for the year it released. I personally consider DC the best but one can always argue SNES for EXAMPLE since it gave people Super Mario World,Pilot Wings and F-Zero. Nintendo is hit and miss. Sony usually misses. Xbox again hit and miss.
Just because I see the next gen as not having exciting launch lineups does not mean I'm apathetic to them period. I like to wait a year or two as that's when the teu lineup starts to roll in. Tho a game like Astro I can't count. It's a built in tech demo game. Face Raider on 3DS or Snail Maze on Master System. People play it on launch and will hardly ever touch it again.
With that, I am done talking about this.
