I live in Indy area as well, and have played a number of Dye courses with mixed opinions on them. I won't comment on all that I've played, but here is a short list:
Brickyard - Not a fan. The holes inside the Motor Speedway are 4 of my least favorite holes to play anywhere. They are overly difficult compared to the rest of the course. #7 is a par 3 that can play upwards of 200 yards to a crowned green with a lot of undulation. If you miss the green, you basically have zero chance for par. #8 is a long par for with water left and a drop-off right to woods (jail). No bail-out either on your approach shot. And for $90, I just don't feel like I'm getting good value. Would much rather play two average courses at $45 than Brickyard at $90. Finally, be sure to find out when they are aerating the greens before booking a tee time, as they do not lower their rates even when their greens are unplayable.
The Fort - Pretty fun course to play. You can score well when you are on, or it can eat your lunch. Greens are usually very fast. A number of holes have a lot of elevation change and tight driving areas, but there also quite a few holes with wide landing areas. I agree with other posts I've seen about how the course can get VERY busy, which leads to slow rounds and the course getting beat up.
Kampen Course (Purdue) - Only played it once after a few days of heavy rains. Despite that, I thought it was a lot of fun to play. Very interesting layout with some really difficult holes, especially with wet conditions.
Bridgewater - Private club. Not the most interesting layout, but still a good course. As it is private and expensive, the course has always been in great shape when I have played it. Greens don't seem to allow for spinning approach shots, but they roll true. The par 3s are rather difficult, while the par 5s are fairly easy. Bridgewater has a few picturesque holes, and a few that are just...there.
Whistling Straits (Straits) - Played there this summer. LOVED it. It was incredibly hot and windy. Despite not hitting the ball well or putting particularly well, the course does reward good shots. The holes along the lake are just awesome to see in person. I can't wait to play it again, hopefully on a day where it's cooler than 110 (heat index).
I've played other Dye courses (Dye's Walk, Eagle Creek, Sahm, Maple Creek, Plum Creek), but I didn't want this post to ramble too much.
