Currently replaying Doom 3 BFG edition on veteran. It's a game that's gotten a lot of flak over the years, but overall it still holds up. Movement and weapons (with one exception) are really good, the sound design is superb and it can get pretty creepy at times. Combat feels unique amongst the franchise, being more a series of individual short, intense battles.
It's not perfect though. Having an enemy appear behind you, or being ready to attack the moment you open the door does get a little tiresome the 576th time it happens. Throwing your view off when getting hit is really annoying as well, invariably leading to the enemy hitting you again and overall leads to a lot of cheap damage. Plus they ruined the shotgun. How do you ruin the shotgun in a Doom game? It's useless at anything other than point-blank range, which on hard difficulty normally leads to you getting hit anyway.
