In the new screens it's pretty much confirmed tennis will be a playable activity. GTA IV we had bowling and shit, we could do all sorts of friend activities. I got to ask, does anyone actually care about that sort of thing? I thought the whole friendship thing in IV was really really boring - except getting drunk, that was fun.
I hope I am not the only one that thinks Rockstar shoudnt waste their time making these sort of activities and instead concentrate on fun things like burglary, drug dealing, raiding warehouses, hijacking trucks full of stuff you can sell on the black market, arms dealing/smuggling, gang wars.. etc. Betting on horses and card games were great in SA, alot more fun than bowling with Roman.
The truth is, Im not that excited about GTA V if its going in the same direction as IV. Instead of "hey cousin, lets go bowling" every 10mins, it will be "hey Ned Luke, lets play tennis".
