I only skimmed through the review, so i might have missed the price, but the MSRP on these is 399 euros, just 30 euros less than a t500rs which is in a completely different league. To be fair, i can find the g29 for 275 euros on Amazon now, but on launch it really was that expensive. Considering that the g27 came with a shifter (a pretty flimsy one, but hey, it's cheap) i still think the g29 was a step back. It doesn't really offer any improvements over the g27 but it's more expensive, even with the discounts. They slapped a bunch of fairly useless buttons on it, dropped the shifter and called it a day. The g27 went for ~230 euros at the end of its lifespan.
Also regarding racesims, i disagree that there isn't much to choose from. There's Assetto Corsa, PCARS, Dirt Rally, Raceroom, Automobilista/Stock Car Extreme, Formula Truck, rFactor 2, iRacing, BeamNG, etc..
