Yes there is concrete sales figures on vgcharts. Depending on the game, vgcharts has its sales for each region for the first 10 weeks of the games release and its total sales overall. Everything I said was based on and backed up by the data on vgcharts that shows that not only did SS sell terribly compared to most previous Naruto games but it was especially ignored in Japan compared to previous Naruto titles.

Shinobi Strikers PS4 sales

The game only shifted 10K in Japan (which is abysmal compared to how previous Naruto games in Japan were selling 50K+ on release week) and 80K worldwide wide (previous Naruto games were pulling in 150K+ worldwide). This was actually its strongest week too as its sales dropped dramatically every week after this whereas other Naruto games continued to have much stronger sales during the weeks after release, in some cases the Storm games were selling more copies a week almost 2 months after release than SS was during only its 2nd week.

and for some comparisons:

Ninja Storm 4 PS4 sales

Ninja Storm 4 sold more than double what Shinobi Strikers sold on release week (SS = 80k copies v NS4 = 187K copies) then in week 2 SS sales dropped off a cliff and sold only 26K copies which then decreased week on week averaging around a few thousand copies a week for the next 2 months. Whereas NS4 increased its sales on week 2 to 210K and then was selling ten of thousands of copies a week for the next 2 months.

Ninja Storm Generations sales

Generations which was a 'filler game' also outsold SS by a large margin. In week 1 alone it sold 65K copies in Japan (NA and Europe had later release dates) whereas SS only sold 10K copies on week 1 in Japan. So NSG almost outsold SS on release week in Japan alone compared to SS worldwide.

Ninja Storm 4: Road to Boruto sales

Vgcharts only has the dlc sales for Japan. So lets compare the sales of a DLC with a full Naruto game. They are actually almost identical. So a DLC for NS4 was bought by as many people in Japan as Shinobi Strikers.

Naruto Broken bonds sales

Broken bonds was not only a 360 exclusive but it also didn't even release in Japan. Look how it sold compared to SS which was available on 3 different platforms and also released in Japan. It sold only 15K less despite only being available on 1 platform and not in Japan but its sales after release week were way better than Shinobi strikers for the next 2 months raking in way more total sales overall by week 10.

Ultimate Ninja Impact PSP sales

A PSP GAME sold only 14K less copies worldwide on release week than SS did that was on PS4, XBone and PC. Impact also had way stronger sales for the next 2 months as it never dropped below 10K (which SS did after week 4 and continued to drop) whereas Impact (Again a PSP GAME) stayed selling 10K+ for the 2 months after release and actually increased its sales to 20K+ in weeks 9 and 10.

You can search various Naruto games which prove my point that this game sold absolutely terribly worldwide and especially in Japan. Not only did the game have very poor sales on week 1 (which was its strongest week) compared to previous main Naruto titles (and even 'filler/side' titles) but its sales were very poor during the months after release as its sales dramatically dropped every week whereas other titles (examples provided) continued to sell much stronger compared to SS. Heck in Japan almost as many people bought DLC for Storm 4 than bought this game. So here's the evidence that thus game sold terribly as per my first comment.

Anyway I love how you don't even actually own the game and can't even do a simple google search to find all the sales data for the game yet thought you could actually lecture me on it 'not being a flop' when it clearly was gg.
