Here is my next batch of 20.  I'll get to my top 50 soon enough.

90.  Pirates of the Caribbean: Battle for Buccaneer Gold (Disney Quest Arcade) - This game is truly incredible.  You are literally standing on a 5-person pirate ship, with one person steering and the other 4 working the cannons.  It would probably be higher on my list, but I've only been to Disney Quest once, and now it is closed down.  I hope somehow people get a chance to experience this unique game again.
89.  H.E.R.O. (Atari 2600) - This game came out during the video game crash, so most people never played it.  To me it was Activision's best game that they put on system.  At the time I was impressed at how many unique boards that they put into the game, and it's just a ton of fun to play.
88.  Wii Sports Resort (Wii) - I thought Wii Sports was fun, but this game brought it to a whole new level.  Sword fighting and archery were my favorites, and I still want to see a proper action adventure game with this kind of motion controls (i.e. like Hyrule Warriors with Wii Sports sword and bow controls).
87.  Donkey Kong Jr.  (Arcade) - When I first started going to the arcade this was my favorite game.  I loved climbing on the vines, and I thought it was cool that Mario was the villain.
86.  The Secret of Monkey Island (PC) - This is probably my favorite adventure game.  The characters, story, and comedy in this game are all just fantastic.


85.  Super Mario Bros.  (NES) - The most important video game ever made is still incredibly fun.  There would be no video games any more without this game.
84.  Excitebots (Wii) - Trick racing + motion controls = yes please!
83.  Kingdom Rush (Mobile) - I love tower defense games, and this is definitely one of the best.  I normally don't like mobile, but this is one of two games in my top 100 that I am willing to use a mobile device for, just to play it.
82.  Mega Man 2 (NES) - What can I say about this game that hasn't already been said?  It is Mega Man perfection.  I really liked the first Mega Man when it first came out, but I could tell this game really kicked it up a notch.
81.  Dragon Quest 8 (PS2) - This is my favorite Dragon Quest.  It's so good that it makes me want to go out and play all of the other ones that I've missed.  Few RPGs are this good.


80.  Actraiser (SNES) - This is a strategy game + a beat em up platformer.  This combo should not work at all and yet it does.  For some reason Actraiser 2 got rid of the strategy part.  Huge mistake.  This game is a one of a kind gem.
79.  South Park: The Stick of Truth (PS3) - Has all the hilarity of a Lucas Arts adventure game, but with RPG mechanics (which I prefer).  Pure enjoyment from beginning to end.
78.  Super Stardust HD (PS3) - A modern arcade shmup.  There needs to be more games like this.
77.  Q-Bert (Arcade/Atari 2600) - Easy to learn.  Tough as nails to master.  This is the very definition of a great game.
76.  Punch Out (Arcade) - I love Punch Out in all of its various forms.  This is the first version of Punch Out that I ever played and it took more than it's fair share of my quarters.


75.  1943 (Arcade) - I didn't take this game seriously until a couple of year ago.  I thought it was basically just like 1942.  Nope, it's like 1942 on steroids, lots and lots of steroids.
74.  Fire Emblem: Path of Radiance (Gamecube) - This is the best Fire Emblem game and the only Gamecube game to make my list.  
73.  Dungeon Keeper 2 (PC) - The best form of a "be the villain" game.  I would love to see a modern remake for this on the PC or console.
72.  Rogue Legacy (PS3) - I love platformers and beat 'em ups and RPGs and games that are really tough.  This roguelike is all of that thrown into one.
71.  Super Smash Bros for Wii U (Wii U) - This is the best version of Smash Bros so far, just because it has the biggest roster.  I expect the Switch version to be taking this one's place next year.

Thanks for the info.

My list heavily leans into the platformer and RPG genre. I I wanted to spread out a bit but those other genres are just not as good
Anyway here is a hint for tomorrow's game.

#49 Its a game from a franchise that only has one official release in America. The main character is a trophy that assists in Smash Bros Wii U.

I wanna guess...

The Legendary Starfy

Yes! But I know him by his original name of Stafy, not Starfy

None of my games guessed so far, so I should add a hint before going to sleep.

#50
a) Turn-based or real-time? I can't decide in this newest entry in the series.
b) This europa is a bit different than europe.

#49
a) Six degrees of freedom!
b) Robotic helpers gone crazy and taking over.

#48
a) Build towers out of people.
b) Level up crazy much.

49. Metal Gear? Castlevania Rondo of Blood? 

48. Shovel Knight?

Pokemon Platinum and Valkyria Chronicles (the first entry made my list) are both spot on! 

I'd never heard of BattleChess before, but it looks really cool, I'll check it out. Thanks for mentioning it :D

This is the first year I've participated and I struggled to narrow down my list. Pretty confident about parts of it but I had a "short" list of over 100 games and I found it very hard choosing one game over another sometimes, especially when they came from different genres. Anyway, I'll put a few hints for my first five games and then go to bed.
