Damn, I'm almost at that 100 icon limit too :( will be deleting the PSMobile stuff I guess. I've got about 40 retail titles now and a bunch of download stuff.
I take it bubble actually tie themselves to Memory cards (apart from physical cards) and so it might actually be more convenient to have 2 memory cards in that regard? Even with the annoying extra boot up time.
Anyway, I caved and picked up WRC4 today and have spent a few hours on it. It's fantastic. Everything WRC3 should have been and more. The handling is great, the visuals are solid, the presentation is much more professional and really does again, feel like the home console version in your hand.
There's much better lighting now and you race at different times of day (dusk and dawn etc.). I have't come across any yet, but this one also according to the box has different weather conditions.
The biggie though, is career mode. There is purpose to play!
Anyone on the fence about it especially after WRC3, forget WRC3 ever happened. Milestone have really nailed it on Vita now. I'm really going to have to check out Moto GP for some circuit racing too. I've a feeling WRC4 is as close to a DIRT game on Vita as we're going to get now. But yeah, I can't get over just how much fun the driving is on this game. You always feel in control unlike WRC3 too.
