I'm a young and dynamic man (lol - in fact an old computer scientist)! I play with computers since ... 1984, my first PC was an Amstrad 464, then, 6128, Atari 512 (only 15 days - power failure), Amiga 500 (the best !), and PCs. I like mostly RPG (TES, NWN, Fallout, Mass Effect, Dragon Age ...), but also Diablo 2 online, Metro(s) and ... STALKERs !!! Un vieux Stalker ... mais pas fatigué (an old Stalker ... but no tired).
The font is too small, difficult to read, this is the same for the gauges.
No ammo counter, and in the inventory we have no information about how many ammo in the weapon cartridge.
Issues you listed ain't really issues.
If you try you can read the text which only indicates type of ammo currently in use. Bars are easy to distinguish from each other red being for health, blue for armor and green for stamina. As for no ammo count its natural to know how much a magazine can hold and to count how many rounds were fired. It increases realism. If you don't like it get other mods.
