I feel like it'd be more accurate to describe it as "less bad than previously" rather than "pretty strong". There's no doubt Splatoon 2 will do well globally, but the UK currently seems to be fairly apathetic to the IP. 

Not only that Splatoon 2 was launched on smaller instal base, but its for 1/3 of price more expensive than Splatoon 1. Aslos, you need to consider current very limited instal base of Switch in UK, Switch instal base in UK is maybe around 200k, Splatoon 2 sold around 28k in first week, that means that around 15% Switch owners bought game in its 1st week. Yes, sales will be better on other markests, but this sales in UK are good in any case.

Nice sales for crash. Two consecutive week at number 1. Nostalgia is a hell of a drug.

I've already considered install base, if i hadn't i'd be describing it as a flop (28k for a major PS4 or X1 release would be terrible in most circumstances). I still don't consider it "good" though. 15% is not a particularly big number when you're dealing with a small group of new (and by extension more active) users with limited choice of major releases. Even stuff like Killzone:SF can  (and did) maintain high attach ratios in the UK in that kind of environment, even with terrible legs once that environment shifted.

Don't get me wrong, i don't consider Splatoon 2's UK launch bad. I just don't consider it good either. It's fine if you do, but it's not a position i can overall find a reason to share.

Not to add to the Splatoondoom but it's numbers could be artificially boosted by the bundle. For many it was the only way to buy a Switch this week.

In it's defence, according to the YTD Amazon charts it's already ahead of ARMS and Tekken 7 without bundling.

Actually all of the UK/European Splatoon 2 Switch bundles came with a download code, so none of them should be affecting the game's physical sales. (Unless this chart includes digital but I'm not sure that it does). That could mean high digital sales for this game in UK/Rest of Europe.

PS4 domination, nothing shocking

GfK has numbers for Snipperclips' download codes. It's possible they don't count codes as part of a bundle but I'm 90% sure they do.

Oh then nevermind if that's the case.

It had one day to sell competitively and it debuted at 2nd place. It released on the 21st and these results are from the 22nd. Think before you type
