It was origionally made for 4:3, so you will need to mod three things. you need to make it fit your screen (16:9 or 21:9), change the FOV(field of view), which will both stretch the HUD, so you will finally have to find a mod for the HUD. All of which can be found by internet search. After that it was great. It is a FPS where you aslo control a squad. Controling the squad was simple and added a twist that made this game different and enjoyable in a crowded genre. I would have given it 5 stars, but this title required a little more work than usual to make it playable. The only question is if you are willing to put in the time to make it playable on a modern monitor.
It seems overwhelming at first. Just make sure to use the tutorial. It at first seems complicated, but the interface will make sence as you progress through the tutorial. There is a lot to keep track of, so i would not clasify this as a casual game.
It is old and you will notice it. For the price you will likely pay, it is probably still worth it. One thing that some prople might not like is the individual missions are not a linear story. Jedi Outcast had better stroy progression. you will need to look on the internet to find out how to modify the config file so a modern monitor can be used. It is simple to do though.
It is a walking simulator. Sometimes I find walking simulators more entertaining than AAA titles. Just so you know what it is. My 5 star rating is based on how much entertainment i got vs how much I paid. Managing the campsite was confusing at first, but is actually simple. I did a couple of playthroughs and will leave it at that. There would be too much repitation to achieve all the endings. Each playthrough was a little over 2 hours. So if you are ok with the walking simulator, it was worth the price I paid just to see how it ended.
