This is the first review I've written for a game, so, I'll do my best.
First off, I want to say that overall this game is short so far, but already really good, and that's in the Early Access. In terms of gameplay it's somewhat simple - so far there's only fighting other ships, entering atmospheres and finding loot to occupy you, BUT it makes up for the lack of quantity with quality:
-The dog-fighting is fun, and you can find ammo for new weapons as loot. Some of the enemies are incredibly strong compared to your little ship, so you have to learn to fight them which is something I love (and watching balls of flame fall to the planet surface after a battle in orbit is one of the most satisfying things I've seen in ANY game)
-Flying in itself is actually a pretty fun experience too: you get different 'gears' that you shift between - basically different speeds. Super slow Docking, nippy Combat, speedy Cruising, and then the cross-the-solar-system-in-seconds Limnal Drive, the game's warp drive (also incredibly satisying to fly in)
-Entering atmosphere is something you have to do to get to the best loot sites on the planets, and it's actually pretty realistic. Not too hard, and you can always make it easier in the settings
One of the nicest things in Rodina is the simplicity of the graphics - the pixelly fire and smoke of fallen foes is surprisingly nice looking, and the Limnal Drive warp too - and the basic models of the ships are fooling; they're pretty lethal, and it's one hell of an empowering experience to land next to a downed battleship and realise your petty gunship is basically a speck of dust in comparison. Trust me, the dev pulled off the ship designs really nicely
And finally, the best part of the game in my opinion: story. In it's Early Access state it's wonderful already. The backstory is immense - the dev has clearly worked for hours just typing it all up, let alone creating it. At every loot site along with empty containers and ammo is a data-stick, each of which gives you a little article of backstory; things taken from books, reports, meetings, communications etc. which sheds a little light on the Rodina universe - the history, people's stories etc. It's so well thought up.
And of course there's the actual story. I was skeptical at first, since this is an indie game and in my experience inde game stories are simple or odd. This is not the case. AT. ALL. The story is good, maybe not the greatest in the world but above average at the least. It actually got me with a plot twist, which was a refreshing change. The story is seriously just... it's worth getting Rodina just for the story.
In conclusion (tl;dr): Rodina is really good already. Short and slightly empty feeling, but what's already here is a really good quality, especially the story. I played the demo 4 times and and have finished the game thus far, and I seriously reccomend it. Despite the Early Access the game runs well (it's only crashed once in my experience at the main menu, and autosaves so much that I wouldn't be that upset if it crashed in game). SERIOUSLY looking forward to future updates, this game has a LOT of potential.
