I don't think I trust or like RTG casinos They just seem to take, take, take The only time I have ever won at any RTG is on a $10 free chip at Casino Titan for $420

I have played Vegas Tech on free chips and won and got paid (in about 5 days including docs) at Slots Galore. I am really starting to like the VT games

My ? is  are the games normally pretty loose? Can you hit it big (on a small deposit)?

Would I have a better chance at a Rival(Vegas Regal, Ruby Royal...) or maybe even Migrogaming (I can only play at Sun Vegas)?

Any comments will be very appreciated

Might be just me, but I truly believe in luck.  If you are lucky you will win and if you are not, you will not win.  I don't believe it matters where you are or what casino you are playing at.  Luck comes and goes. 

I only play at RTG as I like the games.  Haven't found any rival or others that I like.  The games may be OK but it takes so long (in my opinion) to change games in other software.  But that's just my opinon.

It's seems to me that RTG is more for glamour and glitter.  So therefore I wouldn't expect RTG to do much period.  Yet I have noticed myself if you go into a crappier looking casino like vegas tech and even top game.  The games tend to play nicer.  O_o  I guess that goes to show that pretty isn't everything.
I will say though in a minor defense of RTG.  When RTG is ready to pay man it does pay well though, but you have to be that like one in a 1,000 to luck enough to even get something worth cashing out.
