Well, after a few weeks of playing neither, I've had a go at both in the last couple of days. Played GT5, went on to have a go at some of the new seasonals. Got annoyed that I'd forgotten that SRF was locked on and that it took away all feel from the car. Jumped into arcade mode to do some laps to compare to the GTA demo. Got annoyed that I'd forgotten that you can't choose any car in your garage in Arcade, it has to be a favourite. Thought about going through all the menus to select the 370Z as a favourite and get back to arcade, got depressed, chose an M3 instead 'cos it's sort of close. Had kind of fun playing, the AI was both better and just as bad as I remembered. Not as slow, but still ~6 seconds a lap slower, and I lost purely because I started ~30 seconds back in the silly rolling start. Thought about having another game, but the lack of easy options made me turn it off. The next night, turned on Forza 4. Had a look at the new Rivals events, found a nice one for B500 French cars around the Bernese Alps. Had a go in a stock Megane, did pretty badly. Went and bought a V6 Clio and tuned it up to B500. Had another couple of goes and made respectable improvements to my time. Fiddled with the tyre pressures a bit, knocked off half a second. Had a good long run working on my braking points and corner entry angles, got another second. Found that I'd been playing for a couple of hours and it was 1 in the morning. And I'd made something like 400k credits while I was at it. I routinely get suckered into playing FM4 for longer than I'd really wanted to. I routinely get annoyed with stuff in GT5 that I'd forgotten was an issue since the last time I turned it on. Drivingwise, it's close enough that I could forget about it if they were both fun. But GT just makes it so difficult to enjoy. It's like the world's most high maintenance girlfriend.
