I have played many bootleg compilation NES cartridges in my day, and I can safely tell you that 1999: Megallennium 6-in-1 Mega Cart offers more fun in its variety of absurd titles than any of the ones I've played previously. IF ONLY INNER TURMOIL HADN'T TORN MEGALLENNIUM APART ALL THOSE YEARS AGO!
The compilation of games offers RPGs, shmups, wave shooters, racers, and island exploration games involving cute hats, so it basically should make you happy no matter what style of game you like to play. Just don't expect many of them to take themselves seriously, with games like Dr. Moonlight's Happyworld pitting you against vampires on a game show, Xoo: Xeno Xafari putting you on an alien safari where you can get cool hats, or Owlbears having you shoot hostile wildlife that want to interrupt you from eating an apple.
The six games come with a handful of secrets the developer doesn't delve into, but the ridiculous games that you can play right from the start will offer a silly good time. Except for Ultra Frontier QQYYZZ, which the developer describes as "basically impossible." BUT THE CREED OF MEGALLENIUM WAS TO OVERCOME THE IMPOSSIBLE, AND BY GUM, WE'LL DO IT IN THEIR HONOR!

And yeah, this is also a million times better than certain other 52-in-1 games, even if it only has six.
