Allegiance PC Game lover, are there any other alternatives with more modern gameplays and graphics?

For those who loved Allegiance, you know why it attracts, a large battle arena, mining, support, scouting, surgical strikes .. so on.
But the graphics is dated and lesser and lesser people is playing now.

Have any alternative? Even if it’s single player, but with the same scope would be a great suggestion.

If you are going to suggest EVE Online, yeah, I know that already, have anything else? :)
