gaspop: I never played QfG2 (or 3) back in the day. Currently playing through the VGA remake and after a few days I must say there's not alot going on here and I've no big idea of what to do. I've only found three unique spots in the desert and since the game appears to be on time limit I'm worried I'll miss something important. Don't want to resort to a walkthrough either.
The plot and the main quest unfold over the course of your stay in Shapeir. There's nobody to tell you "Are you The Hero? You must go there and kill the big bad". As you stay in Shapeir, new elements and clues appears and not before long, your goal in the game, the reason why Shapeir needed a hero becomes clear. Until then you're pretty much a tourist, getting some well deserved R&R after your work in Spielburg.
There are two tips I can give you to minimize your chances of getting irreversibly stuck in the game, other than saving every days on a different slot.
My first tip, you can't just talk with everyone about everything on your first day and expect to not have to speak with anyone for the rest of the game, most of the game takes place in the city, every new day brings its share of new events and these events gives you new topic to discuss (in the original), add new conversations options (in the remake) and even change existing conversations, for instance, asking the same person about rumors, weather and news will give you a different response every day. It's also possible to get different responses to some subjects when certain events happen.
Don't Panic! That doesn't mean you should talk with everyone about everything every day.
That means every morning be sure to visit the Katta's Tail Inn and ask Shameen and Shema what are the news today, again every morning, pay a visit to the various plazas, Keapon, Tarik, Aziza, the astrologer, Rakeesh and Uhura, to see if something new is happening today, and ask everyone about the topics relevant to today's events, even topics you've discussed before, and tell everyone of your discoveries too. Characters with questionable ethics would also be wise to visit you know who every mornings too and ask about job opportunities, even more so in the remake. By making this your morning routine, you'll be sure to never miss a single event in the game, thus eliminating your chance of getting irreversibly stuck because you missed something.
The second tip: Equip yourself, train your skills and stay at peak performance. Just because you don't have any precise goal yet, it doesn't mean you should rest on your laurels. Unlike the first game where you could train and tackle challenges at your leisure, you won't know what the next problem will be in Trial By Fire until it's happening. So everything you should do when nothing is happening is preparing yourself.
The game comes with a bunch of new tools for every trade, acquiring these tools should be your top priority. If you've played the first game, you should know by now what skills are important for your class, training these skills to peak performance is your second top priority, you never know when you'll need to dust off your skills. Training with Uhura and Rakeesh is also a good side investment if you're playing a non fighter class in the remake, but keep in mind that your class skills are more important. And as always, stock on pills, food and water, a thief should especially stock up on every possible tools of his trade.
TL;DR
Keep yourself informed on what's happening in the city and, at all time, be crazy prepared.
