Nekro is by far one of the most well built early access games so far. At 15 USD, I think it's worth a look into if you're looking for a fast paced fun little game. The game looks absolutely wonderful and whatever content they've published is so far very well done.
Now I saw this title in the Strategy tab so my opinions maybe coming from a different angle. I feel as though there isn't say too much depth in the actual strategy portion. From the screenshots it looks as though you play from a short of an RTS view however, in game it is much more a like to the overlord series. From the bottom of your screen you have a list of summons, AKA spells and actual summons. You use the spells as you might imagine and you plop down your minions using blood a reasource harvested from the enemy units. From what I've played, you can only issue very general orders to your minions, you can order them to attack and thats about it. I suppose there's some depth in the fact that you can say chain your minions and your own ablities. Playing as the support/healer caster type, I issue an attack or rather swarm order to my troops then throw down a healing potion at the enemy greatly enhancing the effect.
In the RPG vain, again the game is fairly simple at the time being. At the start of your campaign you lock into one of the currently three hero classes for the rest of the campaign. You can upgrade simple portions of your class such as the amount of damage, health and reasource caps after each mission. You can also gain item recipies which will allow you to equip some interesting items which can be used once per mission to great effect. I was a little dissappointed by the unit selection though. Over the course of missions you gain the oppritunity to unlock new minions, often there is a choice between two mutally exclusive types. However after about five missions into the game you start to run out of choices. The game doesn't seem to have the later minions done, so once you finish the first two branches the choice portion dissappears.
