The best bit about xenonauts is that it is an awesome port of a classic game with updated graphics and a few cool new ideas and changes.
The worst bit about xenonauts is that it is an awesome port of a classic game that was not implemented fully. So much of this game is half way done and not fleshed out fully.
Let me explain.
It's prettier than original x-com... if by prettier you mean higher resolution. There is no way to rotate the map, no way to zoom the map in or out (well... you can change the resolution i guess), no minimap, fences and doors obscure everything behind them unless there is a npc or player model on that square... the list goes on.
The geoscape is a mess. It's a flat projection of the world that takes as long to travel around the pole as it does at the equator and radar ranges are perfect circles. This would not be a problem except someone decided to be clever and program in a realistic day/night transition that even moves up and down with the seasons. It's not game breaking, gameplay is balanced around the flat map and perfect circles...
Yet I can not get over the realistic day night line. If you're going to do one bit right, you have to do all the bits right, not half of it.
You can set things on fire! But there is no incendiary ammo, and things you would expect to burn (hay bales, wooden buildings) don't. Once again, it's a lovely mechanic ripped form original x-com that is implemented half way.
This basically applies to every single item in the game. Research, manufacturing, base development, combat, tooltips, in game information, etc.
I'm enjoying playing this game... in short stints. If I play too long the flaws grate too much and I get frustrated with the game instead of enjoying it.
If you can overlook/don't notice the flaws xenonauts is a solid x-com remake and is be a lot of fun.
