10/10 concept.....with some minor cautions.
If you are into resource gathering/building games then this is definetly the game for you.
It is beautifully designed, with game mechanics that are our of this world ;). I very much enjoyed the first few times playing, however i have noticed as few things that i would caution you to either to consider prior to buying or prior to playing for the first time.
first i have heard from people who have played the game that is it almost tediously easy. however i must have started playign after the patch because i found the game so grueling at night that every playthrough ends up exactly the same:
Day1-collect eden, collect materials for building, then build a base
Night1- continue collecting maerials for building because NOTHING will attack you the first night (unless provoked)
Day2- keep on collecting and building (dont forget to upgrade eden with spare material)
Night2- Crap your pants as onslaughts of aliens attack from all sides; barely survive
Day3- cry a little as you see all the work put into harvesting and buiding was just destroyed in one night, but you continue to collect and build anyway.
Night3- stock up ammo and energy because you will die. and if you dont, you will be left with a 80% destroyed base and will most certainly die on Night 4.
So, although it is fun and exciting the first few playthroughs, eventually you will get discouraged because everything you do will all end on night 3 (possibly 4). And if you were wondering about more specifics of me trying to survive will no prevail: Ive tried mulpiple "strategic" base locations, (backed up againt a mountain/cliff, away from enemy hives,up high where they cant reach me) but they get you either way. not only do they seem to spawn in on my base at night, but it also seems that killing one of there hives (which should stop them from coming from said hive since its ...well...dead) doesnt not stop them from pouring in from that dead hive. I also tried to purely harvest and save resources from day 1 until day 4 then build a grand fortrace thinking i would be ahead of the game and they wouldnt be able to take out a large base with walls and blockades and six turrets and me ....but they did. they destroyed everything. and killed me.
I know much of this sounds negative, but i truly do enjoy the game. it just has some quirks that make it hard to keep replaying for me personally. i really hope that the creators keep doing a great job and continue to progres with this game.
One last thing....
If you were wondering what i would want to be better or worked on, this is it:
-more varied % for harvesting . ei. maybe a different type of tree that is a higher percentage of the wood (protanium or whatever) and rocks that would all range in % not just 25 or 30%.
-not easier aliens, just more timely placed or spaced out. The first night being alien free is sweet, however a barrage on night 2 and getting harder form there is kind of sudden. maybe ease into heavier waves or more aggressive aliens? it would deffinetly increase my play time and willingness to go to such lengths to build a solid base.
-better turrets. i know this one is odd but i have run into a problem that i dont really like or trust turrets to do their one job, which is shoot at the enemy. Which i cant trust them because they dont seem to do much damage anyway and only half the time they even work; i feel like an alien needs to be directly in front of a turret and not moving to be able for the turret to do any real damage. in the end im just lapping my base killing everything i can while i hear the turrets turn on and off for no reason. can turrets just be on and on guard at night and off during the day? cuz that would be pretty cool.
-a different "start" location at random. the map doesnt seem to change and i pretty much know where to go from the start so maybe making the pods land in different areas of the map would be cool.
