Depends on your gamer tastes. I have a tendency to prefer original companies such a Nis, monolith software and Tri Ace but they mostly produce Rpgs and tactics.
I'm mostly geared to Bethesda and Blizzard Entertainment. Both never failed to impress me with their releases. And now Bethesda is broadening their horizons with Brink and Hunted, so it should be very interesting with how things go.
Everyone should be impressed with Bethesda. If they haven't, then they need to play Morrowind. If they do not have the money, I will front them the money.
