This game sounds very interesting. I'm defintaly gonna pick this up. Is it like Warioware you you only play little snipits or are they full fledged games? Also are these made up games that are similar or are they real games
I haven't played Warioware so I can't really comment on that. If you read the preview I did, I think that'll answer much of what you ask.
http://www.specialtygamer.com/features/previews/retro-game-adventure-is-a/The way it works is that the Arino's evil virtual alias, the Game Master gives you a set of challenges for each game. Like say, "kill 2 enemies with one jump" for example. You play to beat those challenges at first, but the COOL PART is that when you beat those challenges, it unlocks the game in Freeplay mode, and the game gives you a new option (titled... Freeplay) that allows you to play the entire game so each in-game game is
an entire game in itself!!!
The games are all original, but look to be based on NES era games - and growing up on the NES, I can see them on a NES. The graphics, sound, look and even the details feel very true to the culture.
The game is made by 
- so I believe just saying THAT, tells you of its quality - as

were the ones that did all the classic arcade games I grew up with.
If you read the in game magazines, the games often have

-like controller codes, like for example to press up, up, A, A, B, B and you get your character fully powered up in one of the games.
So far, I played the shooter game which has a Galaga feel. The arcade action game is like Mappyland/Burgertime, sort of platform survival - kill all the enemies to go to the next stage. There's an RPG in the game, which I haven't gotten to yet, but that interests me very much - as you'd probably guess of me. Screenshots of it on their website give it a Dragon Warrior type of look.
I can tell you this - Retro Game Challenge feels like an accurate cultural reflection of kids growing up in the 80's. The game is very much about the setting - and yet the in-game games (that I've played so far - I just got it yesterday!) feel to me like they would stand on their own. The ninja game I like enough that if it was a NES cart, I would be interested to just buy it. I'm telling you I was genuinely impressed by this - and that's coming from someone that is used to all these "retro" games coming out lately so I do tend to be critical on games that I view as more contrived or marketing than accurate. Retro Game Expo feels very well thought out,
without being

over-done.
I'm trying to get thru these reply posts here actually to give myself a mid-day game break to play it again!
