Triverse writes, "DC Comics have a very wild hit or miss track record with gamers over the last 20 years or so, some hits (mostly Batman releases) and quite a few misses (some so bad they didn’t even make it to release). Perseverence is something developers have with this comic license though and it seems there is a line to develop games based on comic IP’s owned by Detective Comics..."
Also, it looks like Xmen Legends.
I was reminded of Marvel's Ultimate Alliance since that is the closest game I remember playing like this- could be off though since I haven't played this Justice League game yet.
