I do think monstser rancher is a good game. I've played 2,3 and 4 but 2 is by far the best. I also played the card game and it was pretty good and addictive. I'm not saying pokemon is realistic but the breeding system is complex and unlike monster rancher calculations are needed to determine IVs which determine how good your stats can be like in moster rancher. So you also have to choose wisely when breeding in pokemon too.
fayt lingod - I tend to stay away from ubers because I think they're too strong but they are fun to use every now and then. I've never EV trained an uber though. It's too hard to get good IVs on an uber.My favorite uber is probably darkrai though.
