No idea. Is Red Alert a classic game?
Will more hints follow?
Edit: Lights out? https://en.wikipedia.org/wiki/Lights_Out_(game)
Not sure if Red Alert is a classic game but could be fun. I wonder how Lights Out could be multiplayer

Is it still a classic game this year?
Hmm I also found that post, but then went digging for the quote.
The guy misquoted a bit in that post as you can hear from this vid:
Finally… I’m glad there’s movement here…
The Entelect Challenge is always a highlight…
I have no idea what this could be. But I will be watching…
Always watching…
Yes. We have always done classic games, specifically retro games.
Also very excited about this. Are you guys willing to say how long we still have to wait? 
I’m glad you’re looking forward to it. We’re aiming to launch around the end of April 
It seems to hint at some sort of strategy game, with the Red Alert and Age of Empires references.
Maybe something along the lines of https://en.wikipedia.org/wiki/Artillery_Duel could be fun.
So the theme is definitely strategy, with this warcraft quote. Tower defense?
Tower defence would be rad!
Strategy is definitely the theme, like always
This is something that I’ve always been interested in doing… really looking forward to this one.
Tower Defense would be the most perfect Entelect challenge ever… I think I mentioned that in a email sent like 2 years ago or something… I have no idea how it would work. But Im really keen for what is to come this year if this goes the way I feel…
While you wait, try this challenge: https://codebees.net/
That looks interesting, I like the idea. Perhaps a possibility in future for the Entelect challenge to have an always running massive online world.
