I'm confused. Are we still talking about Volition?
I went on Metacritic to look up the scores on their games:
Descent: FreeSpace - The Great War (1998) - User score 8.0
FreeSpace 2 (1999) - User score 8.8, Metascore
91
Summoner (2000) - User score 7.8, Metascore
78
Red Faction (2001) - User score 8.2, Metascore
78
Summoner 2 (2002) - User score 8.4, Metascore
76
Red Faction 2 (2002) - User score 5.7, Metascore
64
The Punisher (2005) - User score 8.5, Metascore
67
Saints Row (2006) - User score 7.5, Metascore
81
Saints Row 2 (2009) - User score 6.8, Metascore
72
Red Faction: Guerrilla (2009) - User score 7.6, Metascore
82
Red Faction: Armageddon (2011) - User score 6.7, Metascore
75
Saints Row: The Third (2011) - User score 8.2, Metascore
84
Saints Row IV (2013) - User score 7.4, Metascore
86
Saints Row: Gat out of Hell (2015) - User score 6.1, Metascore
66
Agents of Mayhem (2017) - User score 5.5, Metascore
70
I wouldn't exactly call their legacy bad. Their last 2 games have been disappointments, that's all.
