Just bought games, but only two appears in my library

[Sendo Eevpix]

I just got done buying five games.
Sonic The Hedgehog 1
Sonic The Hedgehog 2
Sonic The Hedgehog 3
Sonic The Hedgehog 4(Both Episodes)

Yet I gone to my Library to download the first three, but the only games that shows up are the Terraria, Evoland, Sonic the Hedgehog 4(Part 1 and 2), and a bunch or random games steam is usually trying to advertise to me. I try using the search tool to try and find the games, but Steam can't find them in my Library. When I go to the store page for the first three Sonic games, the store says I own them.

Is there some screw up?

Some of those are DLC for Sega Genesis & Mega Drive classics. Check your game library for Sega Genesis & Mega Drive classics, right click, properties, DLC tab.

So I have to buy Sega Genesis to actually play those three Games? -w-

On the store page it will tell you if you need the original game to play it.But no you can not play DLC whitout the game itself.

... you automatically get Sega Genesis & Mega Drive classics upon buying the "DLC". Easiest way to solve this, actually look at your steam library instead of guessing.

I was asking, because Steam likes to load my library with games I haven't bought or with 2-3day trial game play.
