Unusual mechanics and minigames

-Yup. You've probably seen my idea for using the omni tool to make hologram mini games. Basically, I was thinking they can make the omni tool like an iPhone in Mass Effect lore. you can collect little mini games to use it for like the pip boy in Fallout 4. Mass Effect Space Invaders? or Mass Effect Gwent?

-Would also like to come across a space pirate or raider outpost/colony where they have a gladiator arena. The story could have us temporarily enslaved or caught having to fight in the arena, but afterwards you can bet on fights between pyjacks, krogan, space bears, etc.

-Shooting range on the Nexus is a must.

-movie theater that directly connects to your twitch account would be a cool feature. Cool to watch Multiplayer but from 3rd person point of view

-I still wish they had their own version of chocobo-like creatures to ride on planets and participate in races. The creature could be kept in the docking bay on the tempest after you rescue it.

I also want something completely weird and awesome minigame or activity to do on the Angara homeworld. Pod Racing anyone? Or again Mass Effect lizard like chocobos.

They have to have some kind of professional sport.  Would be neat if bioware create something like FFX did with blitzball.

I'd love a cooking minigame or a card game.

I like mini games. Didn't care for Gwent all that much, so I'd pass on something similar.

I love the cooking idea from Link"Guess"ski. (still having trouble tagging.) I liked those little cooking moments in ME3, too.

The casino stuff was fun. Qasar in Flux and the stuff they had in the ME3 casino as well as the arcade games. That claw game.

I'd like to see the squad mates sit down to a friendly poker game now and then, too. They could act like Poker night is a regular event for them.

It would be cool if the Angara had a native sport/game that we could partake in at our leisure on their homeworld(s).
Racing anyone?

I honestly didn't like gwent either when I did a full play through a few years back.  After talking with a few friends about what they did, I decided to give it a second go on a fresh run.  Treat it like a pokemon deck where you are trying to collect the cards to build this ultimate deck (brings back memories when it was a craze 18 years ago).  You actually see the decks getting stronger and you start to create your own strategy.  You can play the entire game basically hunting down gwent cards and playing in gwent tourneys.  I've had a blast with it.    

We need some board games or something in our cabin so we can invite our squad over to play with us.

I definitely hope there is some silly stuff in there. I'd love if your pet Pyjak got into trouble around the ship or if there were a club or entertainment part of the Nexus where you could hang out with crewmates.

My big hope for ME:A is that Bioware will build activities you could do with your crew that were added in ME3 and the Citadel DLC. I loved seeing squamates chat to each other, sit in the bar drinking or being able to do an activity with them.

I'd like to be able to initiate the activity rather than only being able to do it once. I'd like to be able to invite whoever I like to play Quasar or whatever.
