This is how it SHOULD have been all along
One of the most disappointing Wii U launch titles is undoubtedly Namco Bandai's arcade-to-console port of Tank! Tank! Tank! Not that I think the game is necessarily bad -- I loved my time with the original arcade cabinet -- but expecting people to plop down 50 bones for such a shallow experience is borderline criminal.
Thankfully, Namco Bandai has acknowledged its missteps and decided to make the European eShop release free-to-play. A basic pack that includes Monster Battle, Free-for-All, and Team Versus play modes is now available for free download, but you'll be limited to three play sessions of each mode per day. DLC packs with extra levels and modes can be purchased for a temporary price of £1.59 (~$2.46) apiece -- they will climb to £7.99 (~12.38) after February 28 -- and snagging any one of them will remove the play session restriction.
This free-to-play model was actually how the game was originally positioned in Japan. Why did the rest of the world get screwed over? In any case, I hope Namco Bandai decides to do the same to the American eShop version.
