While very different from the RTS game I played on the PC, the Playstation version of this game was pretty neat too! I don't remember actually being any good at it as a child compared to the RTS and I would use the invulnerability cheat (that websites never told me what it did, they just said to enter in a code and it looked like my vehicles would have like 1HP but no, they were invulnerable)
But I did enjoy the gameplay and the progression of story.
Oh and of course the music. When you began most levels, it was very appropriate to have it begin with Spirit Of Man for the leadup then you switch to Eve Of War or let the soundtrack progress naturally because it's all good either way.
