So my dad has a decent collection of games he played while in college and later in life, mostly WW2 themed or historical. He still has an interest to play those but mostly time and responsibilities limit him. It's been probably decades since he's bought a new game though and I'd like to gift him one. I'd like for him to get a taste of modern board game design with a theme he enjoys. I definitely share his interest in theme so I'm not a stranger to some of those strategy games having played a few while growing up.
Anyway I'd be interested to see if anyone can offer recommendations based on this. It would be very important for the game to be able to be played solo since apart from me he wouldn't play with anyone else. Some games in his collection are :#Eastern Front,#Panzer Leader or#Panzer Blitz: The Game of Armored Warfare on the Eastern Front 1941-45. There's also another Roman empire themed I can't quite remember the name, I'll edit later.
Edit:#Conquest of the Empire is the name
