Yeah I wasn't much a fan of the combat system either. I've never really liked it when video games do such literal translations of pen & paper dice rolling systems. I mean the basic underlying systems, sure, but nothing takes me out of a combat experience like firing a blaster volley at an enemy stood out in the open not five meters away and having "miss-miss-miss-miss-miss"
appear over their heads.
You get used to it though and it didn't stop me from finishing either game. I just prefer the way they approached combat in Mass Effect which is skill based and stat enhanced, rather than being all about the stats and d20 rolls.
