Speedo-a big nono for me, ok maybe a small digi one in the hud next to/below your health then ok, but a huge analogue one will just take up too much room and will be distracting
More famous voice acting- I would choose quality over fame and i hope rockstar find some more unknown talent like maylay, his career will be big and successful all thanks to GTA, although famous i think samuel l jacko did a great job so yes famous talent is needed in a way
