It can be a good thing, not all races can easily reach you until they made starbases, all you need to do is build a huge army in your isolated area, and send it to the planets you think are best.
PS:Can you upload the map image here?I'm curious to know what it is.

[EDIT]
Also, my memorable experience was my first game, I fought the drengin,unaware of them building a military, I only had 1 planet, I decomissioned my colony ship, the drengin colonized all the planets, but their tech was slow, I built a army so huge, it was 50 parsecs wide, only 15 transports, one planet, I felt like I was going to lose, by the time I captured one planet, I fought my very first ship, and this was on the dread lords game, not the ultimate edition, I have bought both of them. Anyway, when I colonized my first planet, I fought my first ship, thinking it was easy, I lost 2 ships fighting it, but they only had 16 planets colonized, they only took one of their planets back, and it was their 2nd last one, I made their homeworld be colonized last, the game lasted,... 6 game years, and on the last planet of theirs, I had 6 ships, in one fleet, they had 10 ships in one fleet, I felt like I was going to lose, but the outcome was my first close call, my ship had 1/24 hitpoints at the end of the battle, and I defeated all of their ships, then I sent my last troop transport, I won, this my my memorable experience that I will never forget, I remember the game forward, backwards, I remember how much I didn't know of the game, I was a lucky noob with a close call, nearly a hero to my people on the game. Also, first planet was also Isolated, I done something harder than you, and tell us what settings you put on your game, what races, what intellegence you put on them?????
